Comes down to Picking your poison.........A recurve and vacuum canister delete would be the cheapest way to do it. I run the Stock dist with a stage 2 Curve in mine done by Don at 4secondsflat with the canister deleted.
I have a 410 stroker, 256@50 intake 260@50 Exhaust Flat Tappet SOLID cam with .618 lift on the intake and .624 on the exhaust. 10.20:1 Compression.
Initial timing is 24* all in at 2800 rpm is 34* total timing. Mine idles at around 1150 rpm clean..fwiw
