is it possible to use any of the f23a's crankshaft on a h22a1 block? i see that it has 97 mm stroke which will give more torque correct? will anyone disagree with this swap?

 

or will the h23 with 95mm stroke be better?

 

f23 wont fit h22a1 block. the f23 has 55mm mains like the h22a4. h22a1 is 50mm.

 

the mains are the thickness of the crankshaft that's bolted between the block and the girdle correct? what do i have to do to change the mains? do i just have to and resurface that part on the block and the girdle?

 

you can have the block machined to fit the bigger mains

more stroke should make more torque, just make sure you punch all the numbers correctly so you don't have pistons hitting heads and valves, etc....
