My 57 T'bird has an .80 over 312 with an Isky 300 series cam, G heads ports cleaned up hardened seats, and stainless valves. Borg/Warner super T10 with a special wide 2.64 first gear and a 2.73 rear. I'm running an original 2x4 manifold with twin throttle body fuel injection. It wants to run quite rich to run smooth. I'm getting 10-11 mpg. What are you guys seeing from your y-blocks in your cars? It looks and sounds great. The car makes seemingly plenty of power but it is expensive to run. MIKE

Mike, still lovin his 57 t'bird after 53 years!
