Stroker Crank, Will this work for a 2270? Options

What is offered is a Type IV- 78 mm stroke performance crankshaft made from an original German VW forging, shot peened, stroked, counterweighted, machined, precision ground, and dynamically balanced. The main bearings are either .010 or .020 under standard and the rod journals are 50 mm diameter.  If you are building a high performance engine for street or off road, where you want the incredible torque and power of a full counterweighted crankshaft, this is the crankshaft you have been waiting for.

This crank is being offered by a shop that builds off road air cooled race motors. Would this work on a 2270? Or are you better off with a crank that has 55 mm rod journals and uses type I rods?

This crank is priced at $300 which seem reasonable.

Greg...in order to get to the 78 mm stroke, they have to decrease the size of the rod journals as they are offset ground. 50 mm is what you wind up with.

You will need the matching rods and pistons. The rod length is different and the piston pin height is different from stock.

As I remember, the 78 mm stroker will fit into the case without clearance issues (no grinding on the case).
