I figured 1. I have it, 2. it is forged 360 is cast, 3. with the small journals it would be pretty light and lots of dirt cheap NASCAR rods on e-bay with that journal size in pretty long lengths so I could run a light weight piston also.

According to my calculations it could go to 3.55 stroke, is this remotely close? With a long rod in my 340 block .020 over it would be a rev happy 360 ish Also this crank is for a 4spd and a 360 4spd crank aint easy to find. It is just a though since I already have it.
