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?

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.

Shon Herron

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.

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

95Bird

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

95Bird

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.

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.

95Bird

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.

roadtrip120

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?

95Bird

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

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

SS Mark

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
