Big Block Swinger from Oklahoma

I bought a 400/727 from a guy that was going to put it in a Cutlass. His uncle bought him a 454 to keep him from doing it. Guess it's not just us that like to keep it apple to apples. Remember the big stink back in the 70's when Chevy guys found olds motors in their cars? Huge law suites. Seems Chevy people were pissed to find a different GM product under their hoods.
