Reply to "Should I keep the dual point distributor or go breakerless? If breakerless what is the reliable choice?"

FWIW, the versatile Ford electronic distributor's mechanical and vacuum advance curves can be tailored to your needs using stock or easily altered parts. The numbered pivoting weights and limit slots can be changed, in case the 460 Ford advance curve in most e-distributors is not to your liking, or they can be tailored with a gas welder and Dremel tool. I think there are 5 or 6 stock choices, besides changing advance springs. Stock Ford vac-advance cans are adjustable with an allen wrench. There are several articles in the POCA Archives on the details of this mod, including using a fail-proof e-coil in place of any of the can-of-oil coils.

You'll have to do some experimentation on your combination; for instance, with aluminum SVO closed-chamber heads & SVO flat tappet cam in our 10.5:1 351-C, I found best power with 16 degrees initial advance and 28 degrees total. I shifted the whole engine/ZF backwards 3/4" on swapped upper motor mounts and now have lots of room for a big vented dizzy cap and late wires. The small move backward also made changing to a flat firewall access door much easier.
