A Holley 750DP.

Mongoose, the Holley carb and dual points distributor is not really a handcuff. If the carb is worked and the distributor is curved, I wouldn't expect much of a hp difference.

I built a 427 S/O for a road race car. The rules stated it had to be a flat tappet camshaft, so I fired it on the dyno with a known-good MSD distributor, to eliminate start-up variables. We made pulls with it, then switched over to a dual point Mallory and there was no difference in hp. The beauty of the new stuff, however, is how easy you can change things, or the degree that you can change them. You can totally recurve an MSD in about 5 minutes. Not so much with a dual points style piece.

The more engines I build, the more fond I am of "old-school" setups.
