Bolt-On LT1 guys... who's shooting for the record???

Ok, I've been talking with quite a few Bolt-On LT1 folks here shooting for the 11's for quite some time now... Tekprodave and a few others who are busting their a$$es to get the #'s. Hats off to these folks!!! Hitting the LOW 12's & HIGH 11's with a bolt-on LT1 is no easy task by any means. You will not luck into those times. It's all about time & patience... BIG TIME! Those of you going for it PLEASE don't give up!!! I'm telling you a high 11.7 with a Bolt-On LT1 IS possible!!! I know what I ran inside & out and know what the car had left in it before I got kicked out for no cage... 11.7 CAN be done by a Bolt-On LT1 DONE RIGHT!!! Keep going after it folks!!!
For those who say it can't be done... whatever... sucks to be you.
:bow: to the Bolt-On LT1 people!!!
Steve... ;)

props to you my friend..

11.7 isn't that bad of a time for a bolt-on LS1!

What are the LS1/LT1 records?

I always though an LG4 with all the bolt-ons/suspension would be interesting. 14's?! :D

sar2k, can you perhaps let me know the simple thigns you did to run that?my car is in the works to be a bolt on lt1, and im shooting to beat your time! if im not mistaken you have an a4 correct?didnt you run with the belt off?and are you running 1.6 or 1.7 rockers?thanks for the help.was also wondering on your suspension setup.as a matter a fact just tell me everything you did to your car LOL!

who has the fastest stock bottomend lt1 with ported stock heads, and cam. and of course boltons. the reason i ask is that joe overton is designing my cam this week, and he has a lt1 full weight TA ported stock heads and his cam. and it hit 11.05 stock bottomend


sark the 11.26 you ran is with cam and ported heads right.

I'm going for the bolt-on record :cool:

I put down 327rwhp and 349rwtq yesterday at Texas Speed

Last time at the track i went 12.9 @ 107mph 1.86 60ft
(In Amarillo Tx, DA 4200ft, ALT 3600ft)

I will be adding BMR sys parts soon, with that and some pro stars i should make a good run at the 12.34 M6 Bolt-on Record(at a better track , Dallas)

My camaro weighs 3400lb (with drive) What are you weighing in at???

Good luck with the quest

Who put down the 11.7 out of a LT1???

As soon as I can aquire another DD that will haul the 2 kids and wife I will pullling the stock 97 in and going all out for the Bolt on LT1 record. It is going to be a long trip but it can happen. In all honesty I dont see it happening with Herron Performance in 2005. But I am getting parts stored up just waiting on the day I can pull it in and put it on stands!

Shon, at least you got your priorities in order, Family first.

I'm pretty sure that SAR2K put the 11.7 down.

It's tough, but the best for all....great weather will come and go before I get to run hard.

And I know I heard about a 11.9 BO LT1 set up but did not know it was 11.7...I am going to try...all else fails (ie the motor blows up) I will replace it with a God touched LSx motor and pick up a second.....

nooooo, why ruin a perfectly good car, and put a LS in it?

nooooo, why ruin a perfectly good car, and put a LS in it?

When you want to run for ET only and do it bolt on you have to get a lighter motor and one that makes a significant more power stock than the LT1....

Really though, not sure what the future holds, i may carry on the LTx banner instead of swapping but you never know....

If I am not mistaken, LS1's weight 100lb HEAVER, not lighter

Plus there is a faster LS1 bolt-on record than the LT1 11.9

I will be going for the stock head, stock bottom end, stock rear end record this spring. I believe it is 11.86 or so.

Who put down the 11.7 out of a LT1???Nobody has hit 11.7's as of yet with a bolt-on LT1. The number to beat is 11.94 which was done 2 years ago.

EASY!

Not that easy, SAR2K has held the record for 2yrs :bow:

Let me find an auto , otherwise it will just be the
M6 record of 12.34, Im not sure if i can touch that 11.9

Not to change the subject, but is there a best time for a stock LT1 with full emissions and A/C and all accessories? Mine runs 12.6 (7.9 1/8) and passes the visual & sniffer test and blows cold AC. That's at 3500 lbs, some lightening, but far from gutted. Do you think 11.9 is possible with long tubes, open exhaust, AC Delete, 1.6 rr's, some more lightening and ditching all the emission controls (AIR/EGR, etc)? Does anyone have any real numbers on long tubes vs. shorties?

Not that easy, SAR2K has held the record for 2yrs :bow:


Only b/c most dont maximize the bolt on effort and skip to a H/C package and some still have a problem running lower 12s.....

Sorry but alot have tried...most give up out of frustration and in their quest to go fast just take the easy way out. But..its not going to be easy to beat that 11.9 run bolt on only. Steve did it at 3500 lbs..If/when it gets beat..my guess is that it will be a couple 100 lbs lighter.

Exactly, they give up. You can get the Ltx car down to 3200 or less now. So it should really not be that hard....once you get all the bolt ons and the right air.

I say this like it is not a big deal, but having been through my other car and more products are out there that I know of it will be a little easier. My other car with 11.96 with HOT cam and LT4 heads, If this silver one stays in the family it will do that pretty easily...I learned alot from that other car...and it was 3500#s, this silver car should be in the 3200 or less once completed....but like i said before, it will take alot of hard work and wont be anytime soon.

Just put a 12 bolt/9" with some gear and a big tire on it and go for it in a 6 speed. If you can 60' with the auto guys you can outrun em on the top end.

someone want to loan me a stock motor? I would love to put a whuppin on steves times just for the fun of it. :p

Just put a 12 bolt/9" with some gear and a big tire on it and go for it in a 6 speed. If you can 60' with the auto guys you can outrun em on the top end.

How big of gears are you talking?? 4.30-4.56, I am putting in my 4.11's right now.

according to the size slick you want to run. I bet a 4.30 and a 26" slick would do wonders on a stick car. Or a 4.56 and a 28" slick. Either waywith alittle suspension work your gonna be able to launch at 5000+ and should be 60'n in the low 1.6s high 1.5s.

Sounds like thats what i need to do. I guess i got the use out of the autozone clutch. Spec stage two is on the way. Also i need to add a rearend to the list of parts to buy, sounds like it is ready to go any day now

why the stage 2 and not the 3?

I ran some numbers for ya.

a 4:30 gear with a 26x10.5 slick = 114-115 mph at 6200
a 4.57 gear with a 28x9 slick - 112 at 6200
a 4.57 gear with a 28x10.5 slick = 116 at 6200

I think the 28x10.5 will be too much tire for you. You could get along with the 9" slick since its really a 27.3" they just call it a 28. Looks like a 4.30 and the 26" slick would be about perfect. I allowed for 1/2" tire growth on all tires. I forget..how high can you take stock motors..its been too long since I thought about all that. You prolly won't get the full 1/2" tire growth on the small 26 slick..which would be a good thing in this situation. The bigger tire is gonna hook better though and you will get a good bit of growth out of the 28x9 on a 8" rim..so it may be good for the 113-114 range. But you have to decide what gear you can live with on the street. Both would be a blast and you will be 200 rpms higher at 70 mph going from a 4.10 to a 4.56 when your in 6th. Both the 4.30s and 4.57s will be tire fryers on street tires though. :cool:

Good luck man..I always wish I would have had a good rear end in my stock car. My 9" would have been a blast back then..leaving off the rev limiter with my foot on the floor...oh..how fun would that have been.

my buddy has a similar setup as mine with a 150 shot, and his stage 2 dosent slip.

its 400 dollars for a stage 2, & 5 for a stage 3. 100 $ saved can go to tires.

ive already got the 4.11s half way instaled plus they dont make 4.30s for ten bolts i think.

thanks for the info on the numbers.

what do u think would be better? QA 1's or K-member and skinnys up front. i need both but i dont know which one to get first.

they make 4.30s..they came stock in the s-10s(same rear end as in our f-bodys). The reason i ran the numbers if for you when/if you upgrade your rear end. I wouldn't put slicks on the stock rear with a 6 speed no matter what gear you have in there.

Skinnies and k-member will help your et more at your level than the shocks. then if you have the choice later you can just do the front shocks if you can't afford all 4 at once.

So no slicks, drag radials (nitto, bfg, or et dr) over all size 26"ish?

I have some Nitto DR 245/50 r16 and some 26x10.5 r 16 ET streets. I bet the rear end would go if i put hte ET's on. If i could get the dr's to hook them i might get a good time. But 4.11's on my slick track will be a challenge.

I thinking about ordering Weld pro stars skinnies this week, but what are some decent, cheap tires for them? I heard one guy here in town got some for $35., at Walmart or something? Front tire is a tire?

any sticky tire on that stock rear is a risk. That being said I ran mine for 90 thousand miles with so many trips down the track I can't count. Never broke. I stuck to drag radials and walked it out..I didn't dump it. Best 60' was 1.83

Get the pro stars..they will help alot. My wife picked up .2 1.5 mph going from 17s to skinnies same night at the track. You can get 165 r x 15 tires at pep boys. They are for a VW bug. don't tell them they are going on a f-body or they may not sell em to ya. Just get the tire and get them mounted somewhere else. I think they are 25 bucks or so.

Rock on :cool:

Im ordering Welds tomorrow, tires as well, thanks for the major info, and help.

Im running Sunday, mid day. I'll send ya a pm what i run 17x9 vs the pro stars.

Bolt on record here i come,lol, 10 paychecks from now :cool:

Im not sure what Ill run, but im at a 12.7 and im going to put on LT's, 1.6's and a ported intake, dont think it will beat that 11.7 though :)

You cant run the proted intake for bolt-on record :cool:

LS1's can change their intake for the bolt-on records.... :D :D

I sure hope we can I was planning on that being one of my mods for the bolt-on record.... ;)

Not like I will get their any time soon.

Hey roadtrip, are you gonna be at the track this Sunday (march 20th)? Id really like to see that thing run. Also was it very hard to do your gear swap? Im thinkin my 78 TA needs some gears but I don't know anyone thats ever done it.

Ls1's get hp from an intake change, Lt's dont. Unless you sheel out the 1400-2000 for and LTx intake or sheet metal. The ruling is nothing oil based Except the rockers for the bolt-on record.

Ya I'll be there if the snow clears up. I put the gears in my self but i am missing a few tools to install any others. Its not to bad just time consuming.

Sweet ill be there too, in the black 89 formula and ill be with the Top of Texas Trans Am group if you get a chance id like to talk to you and check out your car.

I agree...intake work should be alowed. But thats all I'm saying..hehehehe

Sar2k

how much Hp were you pushing when you set the record??

Race Weight??


How about a ruling on the Intake question, Are we, or arn't we allowed to have ported/aftermarket intakes???? :confused:

I understood nothing oil based, except rockers, but the LS1 have them( I know the LS1's are not oil based). But i figured if you had one then the rest of us could run them if we chose. Just asking to clairify

I don't see how an aftermarket intake would not be a 'bolt-on'. You aren't removing stock engine parts, and it doesn't require any machine work to the block, I fail to see how its any different than adding headers. Take off the old, bolt on the new. I don't see whats so hard about it.

the problem with that is, take out the old cam, put in the new, take off the old heads put on the new, they dont require any modifications either, in that case you will need ALOT more than an 11.9 to beat the "bolt on" record :D

I suppose, but I see an intake manifold as an intake manifold. If you have to drain the oil or coolant to do a job I think thats going past a bolt on.

If you have to drain the oil or coolant to do a job I think thats going past a bolt on.

Luckily the LTx intake is dry so you can pull it without the coolant problem and if I seal up an intake i usually dont do an oil change.....
I have not thought about the intake as an upgradeable part with the stock cam.....

first..there are no intakes out there for the lt1. I would think converting to a SBC intake would kinda put the car in another class besides bolt on and the LTx from steve Q would get you nada on a stock motor. You really have to get up in the rpms to take advantage of his great design. But I think that if you wanted to do something to your stock intake and bolt it back on it should be allowed. Thats really kinda like free mods if you do something yourself. The ls1s are putting on the ls6 intake but we dont' have that kind of option since the lt4 doen't really work on a stock lt1 head.

Exactly what I was thinking, I wasn't talking about putting on an SBC intake, but what would be wrong with working over the stock intake. If the issue is about oil touching it then oil is all over the rockers and from what I understand the LS1 guys aren't allowed to touch the rockers. Hell alot of guys at least gasket match their intakes when they fix the intake mainifold leaks. Since we have no cost effective intake replacements I think that it shouldn't be a problem. If I decide to go for the record and I have a ported intake would that make me the bolt-on + ported intake record holder.... :D :D

I think in the end it is our choice anyway, it is not like their is a committy to decide the rules for what is considered bolt-on. Maybe we should do a poll.

I've been following this thread with a little interest. Not that I'm going for "the record" or anything, just out of interest.

Anyway, perhaps "bolt-on" could be further clarified as exactly what it says: Bolt-ON. Someone mentioned a cam. That is a bolt-IN part. Pistons, rods and cranks are bolt-in parts. You can further clarify a non bolt-on part if it's something where you have to drain the oil and/or coolant and disassemble major components of the engine to install them and they sometimes (but not always) require machine work to work right. Heads would obviously fall under the catagory of non bolt-on.

However, if you classify something as not being a bolt-on because you have to drain coolant and/or oil, then technically you are going to have to exclude throttle bodies because in original form they have coolant running through them. And I think rockers are a gray area: They are wetted parts :D

Here is a bench race for everyone :cool:

I just beat a consistant cammed LT, 12.5 at 110mph , by two cars :eek:

From a 30 roll, he was close to track form. I was on 17x11 Zr1's, i have 15x3.5 pro stars and 245 nitto's for the track. He even has the same 1.86 60ft as me. Sounds like i need to take my little LT to a nice/ lower altitude track :cool:

MAd props Silver bullet, your car runs good

B-Rad

I expected bolt-on Lt1 F-bodies to be more than just 6 tenths quicker thant he bolt-on B-bodies :D Especially since you guys start off with so much less weight and a bigger cam.

What kind of 60ft times are the quickest bolt-on LT1 F-body getting? We are deep in the 1.6s.

All bolt-ons??

It's all in the suspension setup. We (Impala SS's) weighing in at over 4000 pounds are running in the low 12's due to dialing in the suspension. I just ran a best of 12.77@104.5 at 4125 pound last Saturday. My buddy ran a new bolt on Impala record of a 12.36@107.
It's not how much HP you have but putting it to the pavement is what counts.

Hell. We aren't putting out 300RWHP either. Do your homework on the suspension and weight transfer. Keep up the hard work.

How true is this? Suspension is one of the last things most people work on and that is where it counts.I am spending more time on the suspension this time around instead of power.
That is amazing that the bolt on record is low 12s in that boat, heck, there are alot of H/C cars (F-bods at that) not hitting low 12s; CONGRATS!!

I see it all the time at the strip. F bodies running low 13's and high 12's with above 2.0 60' times. They will run me down at the 1/4 mile but when the tree goes green they see taillights.

1.6xxx 60' do feel great. Suspension and weight distribution.
