Case 377 rods

Anonymous-0 · Sep 1, 2014

Does anyone know the specs of a case 377 spark ignition rod and piston.

The pin size is my only uncertainty but someone has that info, the rod journal is 2.750 and the center to center length is 10.5" that should be the same specs as all Case rods including the small crank 504s. The wrist pins size increased as the HP increased.
I believe the latest pins were 1.625.

Big crank engines use a 10" rod with a 3" journal and 1.800 WP size

Thanks Mel, but I believe the apart ignition rods were a diff pin

Yes, I know the later pins were larger, thats why I said the later pins, If you are considering swapping parts around I wanted to let you know the possibilities. I adapted a set of 4 5/8 Minnie pistons to 730 rods by sizing the 730 WP bushing to accept a MM bushing pressed in and sized for a 1 1/4" pin.
