TBI for power?
Got a 91 RS 305 TBI 5 SPEED. If i wanted to drop a 350 in it would the TBI system be adequite for the bigger motor. Assuming the TBI system was brand new, how much power can they handle?

a lot of people have done this. From what I understand it's doable. everything is swappable. you need to run 350 injectors, a 350 prom in your computer, and change the spark and spark module to a 350 setup.

I would say around 300fwhp, stock with anough fuel pressure and tune.
With upgraded intake manifold, ported TB, #80 injectors @30psi and tune around 460fwhp.
There are some guys on here making big 400+hp numbers with TBI, lets hope they chime in.
