I bought a 261 that came with an Albro / Schiefer aluminum flywheel. I am going to be putting this motor into a 49 chevy pickup with an SM420 and 3.55 rear end.

The truck will be a driver for my son. Does it make sense to keep this flywheel on the motor? Will a flywheel from a 235 fit if it would be better to run a cast iron flywheel?
