65 barracuda no bottom end need opinions

64 cuda I know what you mean about being a screamer, my dad had a 66 coronet with a 273 back in the early 70's. My sis used to run the dog dirt out of it, although she did a few nuetural drops in it. Compression #'s are even all 8 cyl. but are only 120 max. I don't think I have 9.3 comp. like my guy thought it would be. Should have went with a set of closed 273 or 318 heads instead of milling present ones, although milling .080 off did make them closed. Thanks Mark
