Hi Ian.....

My understanding is the motor is in a Dart that is all steel except the hood, with bench seat.
60 over 340 block 1/2 filled, small roller, 4 inch crank, and cnc pro comp heads. Compression is 9.5 to 1. Quaker is about 2 tents slower than other tracks, so , IMO, running 10.30's at a "normal" track with no compression and not having a light car is real impressive.
The heads used don't have the pushrods moved over, just a cnc on a "stock" pro comp head. Maybe someone did that cnc other than pro comp, I don't know/ forgot to ask....But I do know these aren't the " trick" head Brett is working his magic on. That set of heads hasn't been put on a motor yet.
