Another thing that I hate to bring up, but is very important. Your distributor is what is known as a "Load-O-Matic" - which relies on a venturi (from the carb) vacuum signal for the advance curve. It was designed for a stock engine and really can't be "tuned" for a different engine. Now, it will run your engine - no question - but will the advance curve be what your engine really wants? I have no way of knowing.

If it was my engine, I'd start looking for a flat-top Mallory with mechanical advance or get a modified SBC style distributor from Charlie NY. I'm not trying to spend your money but do want you to at least know that your original distributor may or may not do the trick (performance wise) . . . nobody can really tell you that it will.

I'd hate to have you complete this great engine and then have it hamstrung by a distributor that can't figure out how to correctly run the advance for it.
