Fatso Crankcases

Move into a bigger cubic inch motor with our Fatso Crankcases, now available up to 4.125" bore. The Fatso motor is unique in that it allows motorists to reap the benefits of a single cam Harley-Davidson® Evolution® engine bottom end and utilize their stock Harley-Davidson® Twin Cam® Top End. Or if you would prefer, put Delkron's new Top End Kit on our Fatso Crankcase. (See Related Delkron Products below).

NOTE:
A pinion shaft of +.250 must be used on the crank assembly.
Connecting rods must have a .927 wrist pin bore to use OE or our pistons (our fully assembled short block comes already set-up).
Stock Twin Cam® cylinder head pushrod geometry must be modified to accomodate single cam application (we offer this service-see notice below).

Technical Specs
These BULLET PROOF crankcases are the same heavy duty cases as our "Big Bore" cases with the stud pattern to accomodate your Twin Cam® top end. All crankcases come with a Manufacturer's Statement of Origin.
