92 chevy truck: I used the throttle body off the 305, I..block..chug

Resolved Question:

i have a 92 chevy truck that was a 305 and i put a 350 in. I used the throttle body off the 305, I used everything off the 305 block. The motor seems to chug and doesnt seem to have response and power like a 350 should have. What could be causing the problem? The 350 only has 5000 miles on rebuild.

I have done the same thing. The 350 uses different injectors with a larger nozzle. The good news is that you can install them in the throttle body from the 305.
