The bottom end got freshened up with keith black hyper-pistons 9:1. Stock stroke and bore. The heads got new valves,springs,retainers and I changed the ford rockers to bbc rollers with studs to make adjustable. I opened up the exhaust pockets alot and smoothed out the intakes. The intake manifold is a marine version of the cobra jet intake. Holley 650?700? vacuum secs. Great low end torque, crane xm270 cam. I'm happy with it so far, just alot of tweaking now.
