sorry Billy.... loved our 4" armed W5 mill. also love our 4" in the R3 Either way I'm also in agreement that "IF" you are going through the trouble to do a stroker, you must want something in return and that something is likely more power. Go for the forged crank of your choice.

fwiw the iron head 360 we kick to the curb and then throw back in the car when our fun stuff breaks USED to have a cast 360 crank. Last time it was freshened there were a couple of cracks our machinist was concerned about. It served us well, but now there is a forged crank in it. Only a high 10 combo so not too hard on stuff.
