has anyone ever put a f22 crankshaft in a h22. I have a h22 with a spun number 3 rod bearing and I have a f22 sitting around. I would like to put the f22 crankshaft in a H22a4 because I have one. The journal is pretty bad on the h22 so does anyone know of anyone doing this. I know the measurements are the same but just the stroke is .17" less than the h22.

 

if i remember correctly, the F22 = 50mm and some of the H22's = 55mm ... although some of the H22's = 50mm. I'm not sure what years though

 

does that follow for the f23's also?
