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.

Been over 10 years....but I remember doing a stroker crank, Rabbit rods and Chevy pistons....great fun. (IMG:http://www.914world.com/bbs2/html/emoticons/cool_shades.gif)

Here, is a pic of a rabbit rod, bushed for a chevy .927 pin, the bolts have been turned around, and the bolts are 3/8 big block chevy ARP Wave loc Bolts, in it's present form, the rod weights 662 grams, it can be lightened at least 100g, the length is 5.355. These are going in my motor next week.

The other rod, is out of a Jetta or Gulf, it is 5.670" long, and the piston pin, is oiled from the rod bearing through the beam of the rod.

My current engine is 105.7 x 75, I was going to have my 75mm stroke crank, offset ground from 2.0 ltr journal size of 1.967 to rabbit journal size of 1.805, taking my 75mm stroke to 78.4mm, but I just got a line on a 80mm crank with rabbit journals, I may go that route instead.

Stroke and rod combinations are limited, only by the imagination
