Help with 440/purpleshaft/Holley

[Rocketman]

I have stock jets on the 3310 with a complete rebuild kit. I have a comp .545 cam but got rid of the Pertronix vacuum distributor and went with the MSD and 6 AL box. Got the idle I wanted:

Oh man, I LOVE your ride. Very well done, sir!
That's what they look like all gussied up, eh?

Yeah, the MP electronic on this one just doesn't do anything particularly well. Way too much vacuum advance, even with initial timing only like 5 degrees advanced from stock. It actually runs/takes throttle better with it disconnected.

I bought this 3310 new (I always used them decades ago on 440's - they really like 'em) and discovered it had 70 jets in it from Holley. Weird. Supposed to have 72's. I still have the 75's I put in it, but they're too much I think. Dang thing will run you out of the shop idling, even with the mixture 1.5 turns out.
Guess I can put the stock 65 power valve back in it too now.
