just wondering if this is overkill....
my friend with the 305tbi is thinking of now swapping to a 350 from scoggin dickey. he wants just a simple stock replacement one, like a 87-95 L05 motor or w/e the trucks and stuff have.
he said he'd leave it mostly stock, the only mods would really be a full exhaust and a cam swap, and a carburater intake with TB adaptor and open air element, and a nitrous kit. along with a new torque converter, posi and gears, should we install one of the holley 670 cfm TB's or will the stock one be fine? i think it'd be overkill to add more tb flow since the motor wont be that powerful... thanks 4 the help

I'd think the stock one would work fine. Get 350 injectors, 350 knock sensor and an '89 chip from a caprice with a 350 and you're there.

would i need just a computer chip, or the whole computer? some1 told me a while ago, that i can get a whole 350 tbi computer from a truck and be fine, can i just get the chip since i think the chip would be a lot less $$ than the whole thing. if i do, can i just get an aftermarket chip designed for a 350 tbi truck? like a hypertech or jet stage II or somethin along that line. thnax!

Get the cop chip from Gm asuming you have the 8746 ECM. The 89 SEO 350 cop chip cost about $50 from gm. Its a good place to start.........bob
