My uncle bought a '56 GMC Truck (9600 Series) (3 Ton) and is unsure of the Engine Size.

Needs a tune up & a few parts.

Any help would be appreciated

Thanks

Could be a 270 then. But if you look on the crankcase just behind the distributor the info should be there.
GMC's of that era ran their own I6 or Pontiac V8's. I don't think GMC and Chevrolet started using the same engines until the 60's.
