Im wondering who is the member who had an A12 block with A15 crankshaft?
I cant find the post but one member here had one done by BigE and just wondering what the rod stroke ratio was?

There is one I spoke to in the past via PM but lost his details
The A15 is possible into the A12 block with counterweights
machined, custom pistons with 26.5mm comp height and a12 rods etc

has rod stroke ratio of 1.48 but supposedly works well

No matter what the rod/stroke ratio, it will run and run well.

esp with short rod stroke ratio will run with more awesome torque and response all the way to redline
