I just saw one, at the local strip, last weekend, at almost 700 cid!
A small block. It is the first motor squared, by Chevy, meaning it has a 4 inch bore, and 4 inch stroke.
Buy a new crankshaft.
Yes.
NO. Not even close.
From the front of the motor, clockwise.

Chevy built a 302 in the late sixties. It used a 327 block with a 283 crank.
That would be a destroked motor, and would result in a 285.
no completely different motor
