The a/c 400 cars had a 4-row, but I believe all the others were 3-row. I'd have to check on that though to be sure.

Yes, I basically run a locked out distributor at 35-36 degrees timing, but instead using a timing computer to retard the timing to start the car, it's all in my vac advance. Initial is still low, and the car starts fine, then the vacuum advance quickly pulls, and the car idles relatively smoothly. With the weights/springs I use, I get around 50 degrees while cruising, and 32 total under WOT.

I have a pretty radical cam, and wanted to disguise some of the lumpy/choppiness, so it sounds like a RAIV cam with 1.5 rockers.
