"One of the greatest old names in high performance engines is Speed-O-Motive. Long known for their stroker engine packages and complete engines, George Ullrich and the rest of the power brokers at Speed-O-Motive are looking to show the nation they know how to make big pump gas power. Their Dart-based combo will push a big 4.170-inch bore and a 3.750-inch stroke, which means we can expect big power on the top end. Will this oversquare combo be taxed to make big torque at 2,500 rpm?

"We have great confidence in our Dart-based 351W combo stroked out to 409ci. Friction coatings will be used extensively, as will low-tension rings. The heads will be hand-ported and a custom solid roller cam will be ground to maximize the torque. We intend to equip the block with roller cam bearings to further minimize internal friction."

The Dart block is a relatively new piece, and we're anxious to see how well the entries using it will do. We know street enthusiasts are curious as to its pump gas potential, and so are we. "
