Hey all. I'm looking for some simple ways of squeezing a little more power outta my '77 2.3 for when I finally get her back on the road this summer. She's getting a Hedman header and brand new exhaust, and I decided that hotter ignition and a nice advance curve might be a good next step. So I'm looking at a MSD 6A kinda setup but... does anyone have any experience with Procomp knockoff distributors? I hear mixed reviews about them, but the idea of paying 1/3 the price of a MSD dizzy is appealing. Are they compatible with the actual MSD boxes? Thanks guys, any insight would help!
