i know there is alot of these posts all the time but i want a good idea anyway.
im doing heads (flow 258 on intake side), xe 224/230 cam, long tube headers with hooker catback, 1.6 rockers, new lifters, electric waterpump, intake is port matched to heads and also possibly getting 58mm TB since intake has holes for that size. madz28 tune.
i have an auto and am getting 3.42 gears installed also.

im thinking maybe around 350rwhp. is that definatley acheivable?

 

I would guess with a good tune & all the supporting mods for heads and cam...

350-360 or so!!!

I consulted my dartboard and it said 341.234rwhp definitely. Or was that 342.134?

Seriously, you're not gonna know until you put it together - there are a lot of variables and every car combination is different.

 

yea i know u can't tell for sure but my goal right now is 350rwhp. i would be happy if i get that. stock my car dynoed 250rwhp 308rwtq just with cai and a bunch of knock retard.

 

I think about 360 with right tuning.

 

it ought to do it pretty easy with some good tuning.
