Bought a car with a Revnator, never felt all that comfortable with disconnecting the vac advance, or their explanation of the magic inside their box.
It didn't do anything wrong, really, so I have it as a spare. Basically a stock 383 street car.
I replaced it with a Standard LX-101, and connected the vac advance. Car seems better but haven't put many miles on it yet.
Later in the year I plan to get it on a chassis dyno for some overall tuning.
Has a kinda-stock-looking coil, but with white lettering instead of the green I remember, apparently it's the MP coil.
