Blkfrd, whats your timing curve like? You said you changed initial, but I was wondering what you are running for total timing and how quick its in.

A good curve, probably 36-38 total all in my 2500 rpm would probably wake that car up like no-one's business if you dont have an agrssive curve.

With my Mallory, and a recent MSD in a 428CJ, they were both new out of the box with very little centrifugal timing and it didnt come in on either until well after 3000 (3500 on mine, almost 4000 rpm on the MSD)

Needless to say the change was dramatic with a good timing curve, both in mileage and power
