I have reciently installed a MSD optispark on my 383 LT1 and want to double check my timing at the balancer since the MSD unit can be adjusted +/-7 degrees. Since I have a keyed ATI balancer with timing marks on it, when I installed my MSD opti I fabricated uo a timing pointer using a piston stop. Now when I check the timing at the crank I read about 27 degrees, about the same timing reading I see on the scanner.

Do I want to make the two timing readings match eachother? Or do I want to set the balancer timing to as close to zero as possable with the MSD opti? Is not the scanner reading ignition timing and I get cam timing on the balancer? I am thinking way to far into this and making my self confussed and need a second oppinion.

I just want to verify that the MSD unit is properly adjusted.

You might have better luck getting a solid answer over at www.camaroz28.com as they have a MASSIVE 4thgen group over there, very knowledgeable. I'm interested to know as well, just purely out of curiousity though, as I have a '97 Z28.

Good luck!
