Twin Cam Engine Build Part 1 of 5
We recently took a Twin Cam “A” motor from a 1999 FXDX out of its chassis at 100,000 miles, broke it down, inspected it, and then sent the lower end to Darkhorse Crankworks (DHC) so its squad of bottom-end experts could rework the tired components. Working with [Dave Mackie Engineering (DME)](Dave Mackie Engineering (DME)), we concocted a solid 107ci top end using bored H-D cylinders and some DME Mega-Sphere pistons, complemented by a DME cam. Both DME and DHC are known for their superior quality and attention to detail, so it was a pleasure to assemble this motor knowing the end result would be a powerful yet balanced blueprinted motor.
