360/904 B&M flexplate

The 318 was bone stock. Had a cracked head so I decided to swap it out and put in a 360. I picked up a 360 from a guy out of a motor home. Put it in and couldn't get it to run right for the life of me. Ended up having low compression in all cylinders . Lowest being 40 and highest being 100. So I pulled it out and getting a stock rebuild. So the 360 is bone stock still just with a fresh rebuild
