sounds like your about to throw a rod... thats gonna be a full motor rebuild...

S***, that's what I didn't want to happen. My grandpa in typical old guy fashion is saying it's valve noise. I have a 225/tranny from a 63 Belvedere and a 318 poly from another 63 Belvedere. If it is indeed rod knock, I'll drop another one in.
