Lets say its 1971, and I wanted to build a 360...

Have you thought out any balance issues with the cast crank? Do you have a correct flywheel for the 360?

Here's my idea for a rat rod. It ain't mine - something I saw in the parking lot of a bone yard I frequent. Yea, it's a Ford ( I think) with a Chevy motor, but it's WAY cool...
