MSD E-curve Distributor Set Up???

Sounds like your Distributor is not set up for a stroker. Sounds like you had that dizzy curved for a 340/360 and just used it on this one. Strokers like alot more Initial Timing than 16*. Reason I say this is I had Don curve diffferent dizzy's for different set ups and the one you are describing is for a Non Stroked motor. His Dizzy's done for a 410 of mine was Initial 23* with 11* mechanical "34* Total" built into it all in by 2400 RPM......I bet your car is pretty lazy down low.

I had a lot of trouble with Don's distributor initially. He had my full engines specs, and built it as I described. When I got the distributor, I could not get the engine to start. After running down the battery for the 3rd (!) time, I finally figured out he (they?) had installed the reluctor in the wrong position, Grrrr!! I disassembled and repositioned it, and the engine fired right up. Best part is that I was made to feel like it was my fault somehow... But at least the reluctor chewed up the magnetic pickup, and I had to retunr it for a rebuild after about 500 miles. I still can't figure out how the reuctor could have been off like tha if they had fully tested it.

Anyhoo, that is how he built it based on the specs I gave him. It actually is pretty strong down low, idles at 850 with ~10 in vacuum. Like I mentioned, I would prefer 20 initial, and may try for it eventually.
