wondering what you guys with 383 ls1s are running? im on my quest for 10s this season

my setup is a 383 ls m6 in a 00 camaro ss.
race weight is around 3400 with me in it.

full umi suspension
skinnys n slicks
9 inch with 4.30s
11.6 to 1 compression
cnc trickflow 225s
ported fast 92/92
texas speed 1 7/8 lts thru cutout
full boltons
and big custom spec eps cam 240/256 .647/.647 111lsa

wondering what fully done 383s will do havent really seen to many of them posted on here there 1/4 times

 

Though I don't have a 383, I see no reason why you can't reach your goals. It sounds like a pretty stout setup. If your cam matches up well with your heads, 10s should be in the bag especially at a 3400 lb raceweight.

 

If you can get it to 60 foot in the 1.40's with you setup it should break 10's easy. Good luck!

383 ls1, 11.4 comp, prc 5.3 heads, 243/251 .623/.623 111lsa cam, fast 92mm, th400, 3450 raceweight. ran 10.4@129 and made 427rwhp.

 

It better run 10s lol

 

I assume you ran N20 to run times in your sig.....If you dont mind me asking, what shot was that with?

 

The times in my sig are with the same 383, but with different heads and cam and a turbo. I did end up going 10.0 @ 134 on a 100 shot though.

 

IIRC reason being why you don't see too many 383 setups is because of the price, usually guys go with 402s or 408s for around the same price as a 383 setup.

 

i made the mistake of doing a 383 but now doing a 408 wish i would have done this 408 before

 

My 383 N/A last year ran a 7.26 in the 1/8th mile with a stock ls6 intake/TB and stock 243 heads. That equals about an 11.3 in the 1/4. Should be able to hit 10s on motor with the PRC heads, Fast intake, 90mm TB and bigger cam. I know I could get there with a bigger converter and an aftermarket torque arm easily. btw my 60fts were consistent 1.56-1.58s with the stock torque arm.

 

I'm currently at that crossroads LS1 383, LQ4 408, or LS3.......Too many options

 

A friend of mine has an almost stock camaro running 7.0's all day long in the 1/8 which I believe converts to the 10 second range in the 1/4
Car is a Stock 02 ls1 z28, upgraded to ls6 intake, ls6 cam on stock 241 heads and ls6 valvesprings, long tubes, nitrous converter and a 100 dry shot. Car only has bilstein shocks and running a 265 radial. 1.5 60'.

If he can do that pretty much stock, I don't see why a freaking 383 wouldn't, lol.

 

Stock 2002 Z28 should already have an ls6 intake.

 

Might be an 01 then, I know he had the ls6 intake installed

 

Has to be earlier, 01-02 had the ls6 intake, 98-00 didn't. Also the 98-2000 had the EGR as well and the LS6 intakes didn't have that.

 

What is almost stock about a set of long tubes, a converter, cam and nitrous???

 

my thoughts exactly. In that case people are running 9s almost stock lol

 

My SBE went 10.92 @ 126 with a stick and I'm sure I was heavier than you. That was at almost 2000 feet. You should be there.

 

My 383 went 10.4 on a 100 pill
Hogged out 853s lol
Victor jr intake
90mm tb
Th400
10bolt 3:73
Full bmr rear suspension
