how much power can you get out of a 350 TBI? is there a lot of mods and parts out there?

 

Is this a engine swap or a so called stock engine??

 

With stock 64 lb injectors for a 350 TBI ( stock 305 is 61 lbs ) you can get about 300 HP at the crank. With 72 lbs 454 TBI injectors, you can get about 350 HP. Keep in mind, the duration of the camshaft really affects the computer and makes it a royal pain in the butt to tune. The TBI computers, being speed density, are even more sensitive to camshaft duration than the TPI speed density computer.

 

you got all the mods any other engine has,,exhaust,heads,cams intakes,new throttle bodies,etc...so decent power is possible,maybe not tpi or port injected power but decent.also wynnjammer superchargers sells a real nice cheap kit(1500approx)for the 4.3 s10 tbi...i see know reason why that wouldnt fit your engine.holler at them..its a low psi kit,i think 6 psi but that will add 60-80 hp..nnot bad

 

its a swap from a 305 tbi

 

It depends on which motor you are starting with and whether you will be adding heads/cam or not. Most people swap over to the LO5 which still has the crappy swirl port heads and nets something around 205hp. I've also seen alot of people swap in L98's and the GMPP 350 HO vortec motor. Either way, you're gonna run into tuning problems with the TBI computer the more wild your set up is. Goodluck!
