I got the rebuilt 360 engine and 727 transmission to my shop a couple of weeks ago and put the engine on my stand. My friend bought the engine to help the wife of his friend who passed away suddenly as she needed some funds. It has Edelbrock heads, Edelbrock Performer intake and carb. It came with photos and receipts for the parts installed and work done. My friend became unemployed and sold me the engine and transmission for $3k. While looking at the engine, I saw a block off plate installed where the fuel pump goes. No problem as they were probably thinking electric pump. I looked in the port, and no pump eccentric installed in front of the cam timing sprocket. Not a big deal as I had a spare. My grandson and I pull harmonic balancer and timing cover off. The builder had installed the harmonic balancer dry. I looked at the front seal and about 1/3 of the seal lip had been rolled and damaged. I had a new one but now I'm thinking about what else should I check. My grandson is enrolled at the local junior college in their automotive tech course. This has been interesting to him. He now knows about timing gear marks, seal, water pump, etc. What I really need to think about now is what else to check. Recommendations?A friend has a stand to put the engine on and run it for break in when ready. I wish I had rebuilt it with my grandson.
