Tim we'll be having another dyno day here soon once I get my engine tuned and broken in. Probably in a couple weeks. That way I can dyno tune your engine at the same time.

on that carb you can adjust metering rods, metering rod springs, pump shot rod mounting hole, pump shot squirters, primary and secondary jets.
More advanced tuning includes air bleed adjustments, air valve weight reduction, throttle shaft milling.
Base timing is essentially the same as an efi car. The ignition curve is adjusted by playing with the weights and springs inside the distributor. Make sure you are running manifold vacuum to the vacuum advance and vacuum advance wont do anything at wot (which it should not)
go read the Edelbrock Tuning guide and have them put the wideband on the car on the dyno. Honestly if you want to do any tuning you are sort of wasting your time and money on the dyno since the dyno does not accurately mimic the same loads placed on a car on the street or track. The dyno is a neat tool but I would personally invest in a wideband and tune it on the street and the track.
I had my car tuned by a professional and he said the same thing Pablo said. We tuned the car with a Lamba, that runs the air fuel ratio on a digital reader for the tuner. The tuner said we would pick up more power on the street. We didnt get to do the street as I had a fuel problem. We where pretty impressed and happy with the power made on the dyno though.
I tuned at Blower Drive Service short Bds, they have a web site. Unsure if he does stock memcals though. Kevin has all the stuff to tune a car on the dyno he has a wide band. And he also helps tuning when you tune with him, and if you go to the track when he goes. I make the same power with Kevin tuning same with the dyno run, same track times switching the dfi over back to the 7730 which Kevin tunes.
