A friend gave me a '56 1/2 ton.
It has a V8 in it which I'm guessing is not original, although I could be incorrect about that.
Outwardly the engine appears to be a Pontiac V8, but it wears GMC decals on the valve covers, which appear to be genuine. Also the engine has early style pre smog crankcase breather system, a cannister type oil filter and a small 2 bbl carb, so it's clearly an old engine. In addition to that the engine mounts appear to be un modified factory mounts.
So it looks like original, but I didn't think that V8s came out in GMCs til later.
Any info on this engine?
Thank you
