a 65 Coronet, with a 537hp stoker small block 500 ft pounds


It’s a small block Mopar, but it has some serious tricks inside. It all starts with a Glidden block and crankshaft, previously used in Pro Stock applications when Bob Glidden went to the Plymouth camp in 1979 and 1980.

Daniel handled most of the machine work, using a set of Molnar 6.125-inch connecting rods and custom CP flattop pistons, creating an 11.72:1 compression ratio when combined with the 62cc combustion chambers in the Air Wolf aluminum cylinder heads.

With 220cc CNC ported intake runners and 2.08- and 1.60-inch valves pushed by mechanical lifters, the cylinder heads are real performers. Transferring motion from the custom-grind Bullet mechanical flat tappet camshaft is a set of vintage Crane 1.6 rockers, which were donated by Randy Malik. Camshaft specs are 249/253 degrees of duration at 0.050-inch lift, with a max lift of 0.600-inch and a lobe separation angle of 106 degrees.

Power is put to the ground through an 8-3/4 rear end, packed with 3.91:1 gears and a Sure Grip differential mounted with Calvert Racing leaf springs and CalTracs

On top of the small block Chrysler is a Holley intake manifold that Daniel picked up for $50 at a swap meet. Another hand-me-down item is the carburetor, which he got from his longtime mentor Eugene Smith. Daniel knows his way around an old Holley and built the 750cfm carburetor with custom metering blocks, and a few internal tricks for maximum power and drivability. Ignition is controlled by a stock distributor, which is assisted by a hidden MSD 7AL box.
