Magnum Adventure

I got my custom cam from Comp Cams last night.....yup...it was ground with the wrong lobe separation angle. Someone doesn't want me to build this motor.

What does the cylinder wall look like?




With piston and rod out of the way...


The rest of the cylinders look great. I didn't see any .020 stamped on the piston. I think this crate motor might pre-date the "seaoned block" series.
