If you're running the 12.8" flywheel, have the extra starter bolt hole drilled BEFORE you drop the motor in and discover your starter won't bolt up to it.

Here's the one I had to drill in a 400 block I was using for a while.



It needs to be fairly precise; not easy to attain while laying on your back cursing at the exhaust.

NICE SCORE!

400 blocks are getting harder to find, this is a keeper. Should be good to 800HP or so.
