what kind of timing curve and base setting did you work out?
I played with the firecore dist then pulled it out. I think the 2nd motherboard in it is going out again. idles fine but has a sputter every where but at idle.
the stock dist has the FBO limiter plate on 18* and initial at 18* with the blue med springs. not as hot with points but runs really well now. will be adding a pertronix points conversion set up in a few days.
I think I am getting 12-13 inches of vac in N with 9-10 in gear with 950 rpm. 12 mpg with it. stock LS 10 3/4 TC with 2.76 gears turning a 29x15x15 M/Ts LOL!
got 6000 miles on it now and it is a blast to drive. with 3" muffs /pipes it scares everyone when rolling up to the gas pump.
I can tell you for fact at 4500 rpm flat out on the HWY it is scary fast. but mostly I idle around 1000 rpm in 3rd rolling 30 mph in town.
what specs did the holley wind up with for jets/PV?
I took the new Jegs distributor out and put the stock one back in. It is a fine unit but I didn't like how much taller than the factory one is and it made things difficult up there with the fuel line and how I have the coil mounted. Initial timing is at 15* with just the factory timing curve and springs for now. The Holley is just straight out of the box for now too. Will play with all that when I get it up to the dyno again.
I would be thrilled to be able to pull 12 mpg! That's awesome. My vacuum is right about the same as yours now. 15-16" in N, 10-11" in gear. I dropped a couple of inches in gear with the converter change.
