5.40 is it possible Iron 408 flat top, scoggin ls3 cnced, n20 solid roller,300 shot fogger, 1050 dominator, super vic intake, 2900 lb mustang, glide, 410 430 gear, 28/10 tire and maybe another plate system if needed. what do ya think?
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

Not really.... I have both sitting in the shop. The Supervictor has much longer runners and is taller.
and NONE of the carbed edelbrock intakes are 4500 flanged. So you'd have to run an adapter.

Ya, I don't like adapting to a Dom from a 4150, not going to gain much if anything IMO.
The CSA of the LS3 Vic jr runners is larger than the ls1 Vic jr. It really liked rpm on my last engine.

summit said i could get super victor ls3 dec. 26. I have a new ls2 block available or should i go iron have a few of those? Anyone need a 5.3 alum ho out of 08 or09 no heads 350$
Strange that neither Edelbrock or Holley has made a 4500 intake for the square port heads. It is a larger market than some of the obscure things they make. Like aluminum heads for an old 409 Chevy. Can't imagine how many of those they sell.

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
