It's The Tops
Heads make power! No one can argue with that, and to make sure there was enough power made, a set of Brodix B-1 heads was chosen. Now, Brodix makes a really good head right out of the box, but these were given to Dwayne Porter, who cleaned up the bowls, gasket matched the intake ports, and polished the chambers. Afterwards, Best Machine touched them with a Serdi valve job, using custom cutters designed by Best Machine. Special provisions were also made to the heads to accommodate additional cooling lines added under the center exhaust ports to help cooling. This extra cooling was deemed necessary for when the 350hp NX Pro Shark Fogger is applied. To finish the heads, Stealth titanium valves, measuring 2.300/1.780 inches, are actuated by the T&D rocker arms and Manton 71/416-inch pushrods. Feeding the monster a metered dose of juice is a Pro Systems 1250 Dominator perched on an unported Brodix intake.

The Results
We can blow a lot of hot air, and tell you the what, where, and how of what we did, but unless we show you the what, where, and how of what we did, it's just that-hot air. So follow along, as we show you just what it took to build enough horsepower to make a '72 Dodge Dart travel the quarter-mile in 8 seconds.
