My buddy's iron 408 with ls7 heads, roller cam, and a glide has been 5.50's in a 3000 lb camaro with only a 250 shot from a single plate kit, so I don't see why you cant run a tenth faster in a lighter car.

what kind of rwhp should it have to be able to run that? this year i had 460 rwhp and 473 tq went 6.4 motor and 5.9 on 175 shot thought that was a little slack but that was 364 in. w ls3s 13.2 comp. three carbs three converters and four cams later stayed 6.4 to 6.5 range and actually three dif 6.0s numbers stay the same. do you guys think maybe the head was not to its potential being its stock bore? something been holdn it back w only a 1.44 60. mph was decent at 108.5 just sluggish out the hole.

Im going to say solid maybe.....
Reasons -
LS3 heads dont have a super victor intake available. Vic Jr intake SUCKS.
300 hit is a good chunk, after about a 26-28jet youre going to start seeing diminishing returns. The LS3 casting is prone to flexing.
Now.... 2900lbs, helps a lot. 28" slick, not a radial or et street, but a true slick will let you get the nitrous and timing in fast. If the chassis and tire can handle all the nitrous and timing on the hit, it would go a 5.4X

Pulln weight out of the car this week, got 25 out in an hour bars inside the doors inner fenders cruise control junk behind inner fender driver side, took th400 out put in glide tube k member for trans, may get fiber hatch,a arms. Anyone have four lug draglites for front? I have jegs brand there heavy. Any other weight loss ideas ? I have one guy I have to beat this year that's why I need that 5.40. It's actually a club with there pathetic 67 Chevelle with 500 plus ci two dominators tubbed. I'm so sick of there mouth and godly status! They call this a street car... They can't run a 40 actually it's overkill.

imo 13:1 364 ci ls3 ( hopefully ported ) heads and only made 460hp you either have junk heads or horrible cam guy that you use
