Hey guys just got my 402 done tell me what you think ...the set up is 78mm fast intake, 1 3/4 headers, true duels , stock maf, 30 lbs injectors , comp cam 247/254 duration 656/595 lift 110 lsa, 12 bolt w/4.56 gears ,m6 , all bolt ons . The car made 476 rwhp and 440 rwtq now that was dynoed with 100 mies on it so i know once the thing gets broken in it should free up some power ,and i still have more left there with the intake headers ect...looking for 500 plus when said and done ......thoughts..

mmhmm, on a m6 it should be kicking over 500 easy, What heads, and I would wager you need an upgrade of injectors and a fuel pump. I have a good friend that does about that hp on a th400, with a 5000+ stall. He is doing mid 10's I doubt your going to hit it. After the exp with his car. But GL!

Well, I'm not much of a tech, so I'm sitting here reading your setup going "They're gonna say upgrade the intake/tb (90/90), headers (1 7/8"), and fuel system because those supporting mods don't sound up to part with the stroker." After reading the few responses that have been posted so far, it's nice to see that all of this reading and research is paying off for me.

i'm still running 1 3/4 tubes on my wheezer. still debating how much a 1 7/8 will actually pick it up n/a.i would hate to drop that kind of coin to realize my 1 3/4 wasn't restricting it as much as i thought. you definitely need a 90/90 though.

Well if your car leaves hard enough a 10 second pass isn't impossible, I am running a 402, times in my sig. Th400 car, 5000 n/a converter, 4.10 gear, et 240 head, eastside stroker hydraulic cam, fast 90/90, stock waterpump, stock maf, 1 3/4 headers with turndowns, and it runs 10.5 every trip to the track, 60 foot's in the 1.4

if the track works it will be an easy 10 sec car
since his previous track #'s posted he has removed over 150#'s from the car as well
what I would like to have seen, but money goes fast![Happy](https://ls1tech.com/forums/images/smilies/LS1Tech/gr_stretch.gif)
ETP 245's
1 7/8 headers
3" true duals...has 2 1/2 " mufflers after the X now
FAST/NW 90/90 + porting
EWP
on the other hand I think the #'s are pretty good and as his budget permits we can move forward with supporting mods and dyno and track test each
hope the weather holds out man and we can rock it Sunday
