Here's my build. 428 A scratch C6ME-A block bored .60, stock 428 crank, stock rods, flat top pistons (compression unknown at this point). Blue Thunder 4v intake, hydraulic flat tappet Crower Power Beast cam, original Holley 428 CJ carb. Toploader 4 speed with 3.50 rear end. Here's the dizzy's I already have MSD 8594, Mallory Unilite 3755301, and a Ford single point vacuum advance with a Petronix II in it. I also have one still with points.
If you were me, would you use one of these or sell them and use the money for something else? I also have a MSD 6AL box, but not sure if it is any good.
I got a lot these parts after my Dad died, and not sure if any of these work. The engine is going into a 1969 Q code 428 CJ Mach 1 that will be street driven to shows, parades, and cruises, but probably won't see a drag strip. Might get the urge to scare a ricer every now and then though. I am slowly collecting original date appropriate parts to restore the car or at least have a restored engine to go with the car, so an original 428 CJ 4 speed dizzy will be in the future.
