Custom CP pistons were made...
Custom CP pistons were made with a "D-dish" to preserve some of the active quench area of the Bulldog heads, while delivering a pump-gas-friendly 10.42:1 compression ratio with relatively small wedge chambers. Studs are ARP.
With the bottom end opened...
With the bottom end opened up, we can see the Dick Miller Racing windage tray, which controls and directs the oil slinging off the crank to reduce oil drag. The oil pump is a Melling unit, modified with rotors treated to an anti-friction coating.
Bottom-end beef is provided...
Bottom-end beef is provided by Oliver 7.000-inch big-block Chevy rods, a massaged factory forged crank, and DMR billet main caps and girdle. The crank and rods received an oil-shedding coating to help them repel oil.
