The Ford Barn - View Single Post - G-series vs H-series Flat Six BH's

A member of the truck forum is swapping out one flat 6 for another, and the BH doesn't appear to align with the new engine's rear face holes. It's a cast iron BH, which would be Truck. It has the two lowest holes for the large bolts (at about centerline) tapped, meaning the bolts come from the front. Only two of the upper holes align with holes in the block. The old engine is gone, so we can't tell if it was a G series engine.

There's no issue on the BH-to-trans side, he's keeping the trans that was hooked up to the old engine and BH. (And it's a truck trans).
