i Got a 350 out of a suburban that i am gonna to rebuild. I was think since i might just build particularly for my car and give it The whole TBi set-up for the intake so i would have to change the computer crap, fuel setup, etc. i was thinking of getting so l98 heads or vortec, i was just wondering if i do this right how much Horsepower do you think i could get?

 

Power will depend on what cam, heads and intake you go with. With the right parts you can make an honest 320hp with a 350TBI. They key is chip work. Without it you won't reach your goals.
