SuperCharged!

The engine is a 1956 Ford 312 Y-Block bored to 3.86” (.060” over). The crank is the 312, offset ground to 3.64”, for 2” rod bearings. The displacement is 340 cu. in. The custom rods are clearanced for cam clearance. ARP studs are used in the mains and heads, and ARP bolts in the rods. The pistons are milled flat, giving it an 8.4 :1 compression ratio. Heads are posted 471 castings, ported by John Mummert for supercharged applications. The cam is a Y-284S, with a duration of 284”, with 1.54 ratio rockers. The VR-57 Ford/McCullogh supercharger was rebuilt by Pat Fleischman, and the brackets, pulleys, bonnet front cover and water pump by Frank Rice of Rebop Castings. The supercharger is set up for 7lbs boost at 5000rpm. Custom machine work (bore alignment, over bore, decking, piston milling, head cc’ed, etc.), was accomplished by Cal Stewart at Stewart Machine in Renton, WA. Custom brackets by Dan Miller. Assembly by owner.

Here at HRCS we took care of making sure the supercharger piping would clear the hood and alternator bracket. The Y-block has a gear drive starter and requires a remote oil filter and cooler.

Everyone at the shop agrees that this is one of the coolest looking motors we've ever installed.
