I'm a bit early, but I'm going to rebuild my 1969 302 this winter. While I was in there, I figured I'd go with a 347. She's all ready punched out .030, she would most likely only need a hone, bearings and a good bath. I'm currently running a Edelbrock airgap manifold with Edelbrock performer RPM aluminum heads. I would stick with the cam (.496 lift)
