Your more than likely right on about the 332 cam. I think that Crane will make one once one has all the other stuff sorted out for ones 368. It all sounds like money to me. I would love to bore and stroke my 368. I am not sure if the HD truck 4 barrel manifold had a much higher profile, than the stock 368. If I can get the parts I need now than I'll look into pistons and rods. The M335 intakes are way out there right now.
I have heard about the tri power set up but haven't seen any ever.
I am looking to put it in my 53 Capri.
