1984 305 to 1972 350 Swap

[thefraze_1020]

I'm getting ready to swap motors in my 1984 Chevy. In it currently is a 305 and a 4-speed with a granny gear (I'm pretty sure it's a Muncie SM465).

How much tinkering do I have to do to put a 350 out of a 1972 in it? The 350 originally was mated to a TH350 automatic. I know I'll have to swap the flexplate for a flywheel.

Will the 305 flywheel bolt onto the 350?
Does an SM465 take a 350 (same bolt pattern)?
Can I swap distributors between the motors, to put an HEI in the 1972 350?
And finally, how interchangeable are the Quadrajet carbs?

Thanks
