No Milt was not wrong....They used an Engineering 455 Block that had more internal webbing. Simular to the later SD 455 block. The Crank Shaft was a well prepared 428 by Jim Cornell. The 455 Bore and the 428 crank shaft stroke made for a 440. Higher reving than a 455 and moved torque up. This was a very light weight car and didn't need low end but need to rev. The suspension couldn't handle it. You'll notice that Milt mentioned the people bet it was a Chevy. That is because they had never seen a Pontiac shift at 6,500-7,000 RPMs before. It almost sounded like a Chevy too. The heads where ported by Butch Elkin at Diamond Elkin. Brian Ballish is to get credit for these engine combinations and assemblies.
