    Will that work? What is the interchange on pistons/rods/cranks between years on the 350?

    I know about heads (pre/pos 72) and oiling system (68-69) but haven't heard about the rotating assembly...

    thanks for the help,

    Not really much difference that I know. The 9 to 1 engine has steel head gasket in 68-69 @ .020 thick which is the compression bump. Piston change and milling block is where to bump compression.I do have 70 hi compression pistons/rods standard bore if interested.
