Hi Misfit: The engine you want to build could be done efficiently with
1. 428 Crank
2. New LeMans rods
3. Arias or Je pistons for the correct dome height for a C/R around 10/1 and 460+CID
4. C80E Cobra jet heads or the late ´63 406 heads that would give even higher compression, cast# C3AE-C, made only for a short time in 1963 as Ford had decided to go the whole nine yards and produce the 427, but you must install the larger valves.
5. The cam that you should use should approximate the old 427 Medium Riser drag cam that was 324 / 324 and close to ,600 lift, solid lifter. Just remember to tap and plug the lifter galleys and to install a ,090
oil restrictor orifice in the
oil gallery going to the rockers.
6. Valve train parts: Go with Comp. Cams or Erson
7. ignition: Go with a Vertex or Joe Hunt mag that are now on sale on E-Bay. The old C3AE dual point will do nicely also with a suitable MSD amplifier.
Lotsa luck ....
