I’ll look at the engine to get the numbers. It looks like a 216 with 2 speed rear. I did drive the truck today for about 30 minutes. 50 mph in high/4th gear is screaming. The dump bed works perfect and I found some original paperwork in the glove box once I got it open. I gotta say this truck drives like a dream. Smooth shifting, tight steering, and it does have the hydravac booster which makes stopping very nice.
