Mine is the 2-ton model, I collected one of their 30% off e-mail only coupons. The engine was completely original to this serial number on the title (and the 2' crack under the manifolds in the block). I purchased it from the original owner family.

I didn't think there was any paint left on it? The new engine is a 54' the PO painted. Good call on getting something instead of the beam we don't want anyone to get hurt working on a bolt!
