As long as the vacuum advance is hooked up properly to a ported vacuum source you don't really have to worry much about the timing the vacuum advance induces unless it pings under moderate acceleration. When you floor it you loose vacuum to a ported source so the vacuum advance is no longe in play. Most I've seen produce anywhere from 50-54 degrees when the vacuum advance comes in.
Ok cool, good to know. As everything without the vac. port connected is dialed in around 1800/1900 RPM I don't think I need to recurve anything. Chime in if you disagree.
The 9.2 seconds is pretty slow, sorry to say. A good converter will knock a couple seconds off that as long as you don't spin the tires.
That's what I'm sayin' I pulled this motor out of a D250 Crew Cab and it feels just a few seconds faster in the Dart, I suppose it shows how important gearing is. The truck was an '81 so might have had steeper 1st and 2nd gears in the 727, and the rear end was probably a 4.10 (ex army tow rig, with 90kph as top speed sticker on dash) as it hit about 4k RPM at 135 kph if not more (this was by ear)
I won't ever hesitate to run a 3k converter on the street again after seeing how mine works. As far as converters go a general rule of thumb is the more expensive ones are better. But I don't think you need to spend $1000 on your setup to make it right. If you really want the best call Lenny at Ultimate converter and have him build you one to your cars specs. It might cost $500+ but it'll be a fantastic converter. If you don't have that much money try a PTC. That's what I run and it works real good. Got mine from Cope Racing Trans.
