I have a 307 chevy engine, and I was wondering what I could do with it as far as swapping crankshafts around, and what size I could come up with, this would be for a hobby stock type car.

You can bore the 307 out to a 4.00 and have a standard bore 350. That is about all they are good for, in my opinion.

Yes, you can put a 350 crank in a 307 block.

Check out the most recent edition of "Engine Masters" by Popular Hot Rodding. A guy built a 307 for the competition and ended up finishing 3rd. The article on him goes through the entire engine, parts, machining and all.

The crank will fit into a 400 block with spacers for a high winding 350.Also some rules call for a 5.0L engine limit or 320ci and a 307 is the best thing to run.
