I have a 1990 Trans Am and I'm looking to swap a 305 to a 350. The car originally had a 350 in it, but when I received it the car had been swapped to a 305 with a carb. I'd like to keep the carb setup but swap it to a 350. Can I use a newer fuel injected 350 and keep my intake parts and swap over? Or will that not work? I'm new to Chevy's been playing with Hondas for a few years. Thanks!

 

Any 350 will bolt right in, they changed the intake manifold bolt pattern a little in 86ish and a **** ton in 96.

I would look for a 96-2000 350, change the springs in the heads, swap in a new roller cam and get a carb intake manifold for vortec heads.

 

L31 crate engine, and the Scoggins-Dickey Vortec TPI manifold. Everything bolts back up, and looks completely stock. Great for the street, even more low to midrange torque and hp than the L98.

It's still going to run out of breath above 5500 RPM, but unless you intend to race the car, you'll be very happy with the way it runs.

 

I'll second this. I love my L31. No need for the TPI intake though since he wants to stay carb. He will just need a carb to vortec intake instead.
