Re: 400 Chevy in a CJ7
One note that I mentioned in the past about 400's; to my knowledge they never came with a 4 speed, and they are externally balanced. This means you can't just bolt on any small block flywheel, you either have to find an aftermarket, or have one balanced for the 400. No biggie, just don't want you bolting everything together, starting it up, and shaking your molars out. I t cost me $60 at a machine shop.
