oh ok thanks for the info i have been thinking about it and i may just start with the d1-sc with some afrs and work my way from there,do u know what the cost of an f1 is though?
Update well i finally got everything together and on the dyno
and the car made 406rwhp/446rwtq with a unlocked
fuddle 3800tc and 3:73 gears with an 8.5:1 compression ratio but i need to get bigger injectors and ill make some more power but i need to break the motor in a little more before i can do that,but now my problem isnt power its traction lol
oh yeah ive decided i will turbo the car but not till some time in the near future

Well you have a good sized stall so youd be able to build boost off the line, so id say on a 402 from what ive heard a T-88 would be good for a 402. I had an informative discussion on this board with one of the members who is building a single turbo 383 and he said he was very close to maxing out his T-76 turbo he was using so a T-88 would be the way to go on a low compression 402. Nice numebrs though NA and im sure they will go up when you get the fuel system and break in time done. What rear are you using right now?

I would consider a 72cc head with a 4 inch chamber. PRC sells these I believe, you might be able to do an exchange if the parts are new.
An AFR 225 head designed for a 4 inch bore, 72cc and thick decks would be ideal imo
I would go turbo before blower. A T76 or T88 would work wonders
You would have a comp of around 8.3:1 be able to run pump gas and make 700RWHP very easily depending on what turbo you went with.
Check out the forced induction website. They have alot of good information.

,so i shouldnt really have any problems with lag if i went with either turbo?im kind of new when it comes to turbos so sorry if im asking dumb questions does anybody make a kit with a t-88 for a 402? There are a bunch of kits for sale in the FI section. The newest one I believe is Hi-Flo, and I believe their kit is good up to a T-88 turbo. However, 1000rwhp is gonna be real tough to obtain on race gas nevermind pump gas. Like Chrispy said you could def see 600-700 rwhp on pump gas on a forged low comp 402, especially with a T-88, however to get to 1000 rwhp on a 402 youd need a massive turbo, which wouldnt be much fun on the street as it would take very high rpms to get it to spool. On pump gas though at say 13-14 psi you would probably see between 600-700 rwhp, give or take a couple psi. Also you can check out the stick at the top of the Fi section as they have a boosted list for 2005, and this shows everyones setups and the rwhp and rwtq that they have plus their 1/4 times.
For the larger bore setups we've been doing the PRC Stage 3 LQ9 heads. The last set went over 320cfm & made 520rwhp in a 402 with cats!! The 233/239 would be pretty small for a stroker, have you considered the TX Giant 248/254?

well i was thinking that but the thing is the motor is going to be turboed and my current h/c combo will be going on my ls1 346 motor which is going into my moms 91 rs camaro so while it would be nice to have that big of a cam i would have no use for it once i go turbo,do u know what i would need to be able to swap my ls1 into a 3rd gen that had a v6
