70 440 6pk pistons, flat top or notched ??? - 11/22/08 05:18 PM
I bought a 70 440 6 PK engine 15 years ago and had it completely redone to the tune of $7,000. I`ve been cranking it by hand every so often to keep it loose. I`m now getting ready to install it and noticed my flat top pistons have a very slight curved line??? maybe from the exhaust vales??? ANY INFO would be grately appreciated.
