Molnar crank and rods. Diamond pistons. Milodon gear drive. I was shooting for 11:1 but I had to go with a Felpro .59 head gasket because my Cometic .40 didn’t mate well with the BMP alum and eddy heads. Chambers were a little big even with a clean up cut . Oil pressure is a little high could have backed it down a little and pick up a couple HPs. Ended up with 33 degrees advance timing
