Another note for anyone interested in this engine. There is no flywheel included. I needed this for the EV conversion. Also, there have been a number of questions on the specific internal details on the heads, cam, etc, etc. I'm sorry, but I did all this and was really into the specs on things way back 15+ years ago, but I don't remember all the details and I didn't write them down anywhere. Jake did a bunch of stuff, but I honestly don't remember all the details.
