Bittersweet new best at VMP tonight.. Post #1 of 1

Awesome track night. only about 50-60cars altogether at VMP in petersburg VA.
Conditions were great at 6pm and only got better as the night wore on. Peoples times were dropping so quickly they were running out of their dial-ins.

Unfortunately for me I only got 2 runs. 1 at 6:05pm and 1 at 6:20pm. There were so few cars ready when I got there i hot lapped pretty much.

1rst run: rolled into it pretty good from 2k footbrake:
60= 1.53
1/8=7.30
1/4=11.531 @ 116.35 car shifted into overdrive 60-100feet before the traps evidently my shift point is set currently at 6200rpm, should be 6400rpm, my original tuner couldn`t remember were he set it and my factory tach`s not accurate.

2nd run: Hit it hard, something seemd to break loose in the rear and it spun a little ways out of the whole, left it in 3rd this time so I could run 3rd gear past 6200 at least.
60=1.69
1/8=7.45
1/4= 11.676@116.86

Then when I made the turn to get off the track I heard a thunk, thunk, thunk from the rear and the whole rear of the car was shimmying. I beleive the 10 bolt zexel-torsen limited slip took a dump on that second launch(200 rear end swap). End of racing for the night.

So all in all won`t too bad, got a new best, know there`s more in it for sure. gotta spend some dough now on a 12 bolt. Get shift points set for 6400rpm in all gears and I`ll be set. Not too bad for a bonestock shortblock LT1 w/ out a power adder.

Also this car still has a/c, power steering, all bumper supports and ran this time w/ 245/50r16`s up front and 255/50r16 MT drag radials out back.

Great times!! Time to pony up to the 12 bolt club, now...I'm going to go to the track tomorrow to see if the 10 rwhp I got with the EWP will get me .1 and 1 mph...Then we'll install the Kooks stepped Lts and see what happens....Nice to see more LT1s going 11s N/A...

Stock short block would mean stock cam too wouldn't it?

Most people refer to the cam being part of the valvetrain. Ie... the upper end not the bottom end, which would mean crank, rods, pistons ect... If you want to be technical about were the parts for the valve train attach to the engine, then the same can be said of the lifters. they would attach or sit in the shortblock. Not to mention the timing chain.

Let me break it down. I have bonestock umolested pistons, block, rods, crankshaft. They have never been out of the car. The upper end, cam, lifters, pushrods, timing chain, rocker arms are all a/m. The heads are ported stock units. The intake is a ported stock unit w/ a a/m TB.

Would you prefer Factory stock bottom end....I think everyone knows what I mean. Here I just changed the title for ya, that make you happy?

By the way what does your car run, mods ect...?

Might want to look at this link:

Here are a few from that page, notice they have non factory cam listed in their engine descriptions:

No need to get all touchy.... lol im just asking. And I have no clue what my car runs since I have never driven it. Kind of hard to drive a car from Iraq. Im sticking to the stock cam and stock bottom end myself and trying to run the hell out of it.

Sorry, it just seemed that w/ this post:

then your coming back w/ this quote:

It's cool man! Hey those are nice times though. I hope to just get into the low 12s with all my mods. If I can break away with a high 11 i'd poop my pants. Check out what i'll be running.

LTs, 2 1/2" duals, 52mm bbk, cai, ported LE1 heads, 1.7 rollers, 3.73s, yank 3600 stall, prostars with skinnies and e/t drags, and about 3200 lb car.

Anyway keep it up man.

Yep, those cam`s certianly come on strong early, picked up a lot of power down low vs my xe 230/236. Our 60`s, 1/8th`s and 1/4`s were almost exactly the same.:cool:

Do you know what the weight diff between the 10 bolt and the strange 12 bolt is? I`m going to be needed one of those...

W/ almost your exact mods (stock internal) in a 3450lb car I went 12.41@109, but my stall was a yank SY3500 w/ a weak str 1.61, so it didn`t get me out of the hole too well. Oh, and unmolested heads...Lol..

So you think with the heads and a really nice converter i can see a low low 12 or high 11? Nothing beats out that time you ran though.

W/ the weight you are shooting for I think those are realistic goals, and you should have no problem hitting it. just make sure you have a 2.5+ str converter. The only single thing that concerns me is a lot of time w/ ported heads, you lose velocity w/ a small or stock cam, which would make low rpm power seem sluggish. However w/ a 3500+ converter at WOT you should be straight. Any reason your not going to match a cam for those heads?

Thanks for the props on my time. The crazy thing is its got more in it. Short shifting at 6200 instead of 6400 in all 3 gears, including going into OD before the traps, plus the run was made at 6pm and the DA was dropping considerably after that. Several people were 1-2 tenths quicker by 9pm that had been dead hooking all night, no changes made other than air. The car has easy 11.30`s in it. But you know what they say, it don`t run it, till you run it....:)

I'm sticking the 1.7 ratio rockers in there which bring lift up to 507/520 with the stock lsa and duration. Should sound as stock as any other long tube true dual car out there with a little more power. I like the sleeper look and sound. If I can break the 11 mark... i'll throw the 125 shot on there and hope for the best. LOL I just like the idea of having a fast stock cam car that sounds like it's slow. Everyone has their thing I guess. These heads have stock valves so i'm not too worried about the loss of velocity. I had a set on my 93 with 1.6 rockers and stock manifolds and it took a best mph of 86 in the 1/8th. I've got some confidence in them.

You got yourself a GOOD running car there. I might decide to call up Joe and match up a cam to these heads once I get it to run for a while along with a fresh bottom end.

Cool, you should be straight then. Stock size valves will keep the velocity up w/ your stock cam, but flow better and make more power. Another Joe O. cammed car has been 10.88 on a stock rebuild bottom end, ported stock heads w/ stock size valves. Of course it doesn`t resemble a daily driver anymore....:D

I'm not sure how much more a 12 bolt weights, but its worth it for the durability and being able to throw what you want at it (to an extent) without breakage...I went from high 1.60s-1.70s to solid 1.55s switching to a 12 bolt and some good sticky radials...I'll get high 1.40s out of it yet...

Alan,
I was curious, I can still drop a lot of weight, a/c, bumper supports, shinnies up front ect...to offset the 12 bolt weight.

What RPM do you have yours shifting at?

Meangreen, 11s are definitely possible with a pretty generic h/c package. Much weight reduction really shouldn't be necessary if low 12s/high 11s are your goal.
