2011年10月25日 · The ignition system is it.. 7A/6AL, Blaster 2 coil, 8981 timing computer, older MSD crank trigger with gold tone wheel, plastic pickup, and a 2 step module. The distributor is an older MSD piece with the large ford style cap.

2006年1月1日 · It will all depend on the input signal, and how many times it triggers the ignition to fire per revolution. Being a 4 cylinder, the 8981 would need to see 4 triggers per revolution since the distributor is running off the crank. If it fired on the intake only, you would need only 2 trigger signals per revolution.

If you currently have a timing control that has a retard, you can remove this control and just use the PN 8981, which also has a single stage of retard for nitrous application. You will connect the Crane to the white wire of the PN 8981 and the yellow wire of the 8981 will connect to the white wire of the MSD 6AL.

Geneguy, I had similar problems in the past. I currently have my distributor locked at 38' total and am using an MSD 8981 timing computer (with an MSD 6 box though) which also has a built in retard of 20' so on startup I am at 18' initial timing. The result is the same as what you want.

2022年4月20日 · The instruction manual (I know, reading the instruction manual is against the Man code, but I do it anyway), it shows a MSD-6 series that has a gray wire that's used for the tach signal, but my MSD 6AL PN 6420 doesn't have a gray wire, but it does have a tach output terminal (with a wire attached) that I assume drives the existing tachometer ...
