Very impressivle looking engines Joe.
Butler Aluminium block, Tiger heads ,BOP intake, very nice.
As you maybe aware i don't know the ducks guts on Ponti's, so could you please explain which part of that motor is actaully a Pontiac produced part ?
And while you're there, in my Summit catalogue, I noticed the World Products engine, that they say is "based on a Ford".
They list the parts, but I don't see too many (none actually) genuine blue oval parts in that either.
