Next I ordered a hard roller blower cam that is a 642-642 lift 114* center line, I also ordered a set of Comp Pro Magnum cromemolly roller rockers, w/ a set of new push rods that fit the new rockers and Brodex heads. After we got some new parts I pulled the motor out of the boat and we tore it down. We preped the blocked by plate honeing, but I pulled the threds out of one of the head bolt holes when instaling the torque plate, so next we drilled and taped the bad hole so we could put in a helacoil.

What we did next is a little diffrent, we drilled holes in the block and installed jets that spray oil on the bottom of the pistons to cool them and help fight detonation

When we had the block preped we installed the Calico coated bearings
