Tech Question
curt schroeder, ashcroft, BC, canada, 68 dodge dart 360
what is a W-2 smallblock? I have no idea. I read about it in the Green Brick article and thought it would suit my Dart.
Curt, it's simply any smallblock Mopar that has had MP's W-2 heads bolted on.
W-2's were the first really high-flow factory heads for the smallblock, there were basically a result of the late-1970's Pro Stock program. Their main claim to fame were totally revised ports, and a unique intake manifold bolt pattern (requiring special rocker arms.) W-0 refers to the original 1968 340 "X" head, and W-1 is generally taken to mean "J" castings where the pushrod holes have been relocated to allowing removal of the pushrod tunnel "lump" in the port. The "W" series has progressed continiously, to the point where some of the newer designs barely look like a Mopar head.
Today, while there's lots of better flowing heads out there, the W-2's cast-iron ruggedness keep them in contention where long-term durability is improtant (read: street, endurance racing, etc.)
