Car: 1987 firebird Engine: 1995 lt1 383 Transmission: 4l60e Axle/Gears: moser 9" with 3.70 | MSD opti LT1 Timing check
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. | | |
