[bascosauce]

The main thing I believe is the boss motor uses 351c heads.

I may be wrong, but I don't think they were not exact 351C heads, I think they were a variation of 351C heads.

The block was also 4 bolt main, high nickel content, screw in freeze plugs, and it was non-roller.

In short, pretty much everything except the cubic inches. It was a true race engine in a street car.
