Hey all. Its been a long time. I am re-baselining things on the Dart. I am running the billet Accel distributor. Anyone have any idea how much mechanical advance this distributor will provide with the slots opened up the whole way? My previous tune is listed above. 18 initial, about 20 mechanical, one, light spring, and then with the vacuum can hooked up around 18 more.

I've used a piston stop to verify TDC on the harmonic damper, insulating and rerouting some fuel lines, and a insulation plate to hopefully take care of the vapor lock issue I've had a few times.

Any suggestions on a baseline tune (lets start with ignition timing for now) for a pretty much stock 383 would be helpful too. 150 PSI cranking compression, stock cam, RPM intake, headers. After I get this set, I'll focus on the carb.

Thanks!
