Maybe it"s Tony rubbing off on me but when I was getting those front rims the other day, I was talking to the 75 year old Massey mechanic that works at the dealer the other day and he was showing me some parts he had set back. Right there on a pallet he had a nice Z145 MF135 engine. He offered me an insane deal on it and said yes it will bolt up and work but the rear end on a TO-20 would never stand it. He said but if you got a rear end from a TO-30 it would be fine. I"ve been searching for a good TO-30 engine, but I can get this engine for less than what a crank and head would cost for a TO-30. I am tempted to do it. Am I the only one that wishes the old Z120 engines had a little bit more lugging power?
