I don't know why you would want to spend money on 305 heads, when you could take that money and buy a set of good 350 heads already beefed up and ready to go.
If the Buick 305 is really a Chevy 305, then the motor mounts will interchange with a Chevy 350.
by the dispacement
Yeah.
Replace it with a 350
No they are the same blocks.Where did you get the mounts on the 350 from? The 305 or junk yard?Is it a new 350 or older 350?
No. It's probably the same thing.
Yes they interchange
Both are strong engines, but the overwhelming consensus is that the 350 is a better engine, and I agree.
