Ok all.
I am wondering what the differences are between the 69 440 and the 77 440.
I've found that the stock 69 had 10.1 compression and the stock 77 had 8.1. What's the difference. Heads ? Pistons ?
I don't see the blocks really being different. I have a well used 69 complete engine but am getting ready to go pick up a complete 77 440. Why is the hp and compression so different.
