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.

Chevy rods are generally too wide on the big end and they are designed to run as pairs on the journal..

There are other rods that can be used, but all of them either cost more or create an engine that is more difficult to assemble.

The TI journal with an H Beam rod is very difficult to beat in price, simplicity to assemble and the powerband they create when matched to the correct cam...

I use the Cunningham rods in only one application, and thats my Powerstroke Bus engines.

Always remember that the selection that you make on one part, will effectively change the selection of every other part inside the engine that works in conjunction with it- just like a recipe for a cake....
