A Must if Spraying No2

Summit RacingSummit Racing Verified Purchase

Great product to check your rotor phase. Critical when retarding your timing precisely. One recommended tip is to use locktite on adjustment screw. Mine came loose even though I used the conicle washer provided.

Excellent For Phasing The MSD PRO Billet 8356

Summit RacingSummit Racing Verified Purchase

I purchased this to use my MSD 8356 dual pickup Chevy distributor with my FAST EZ-EFI 2.0 fuel injection system. My 8356 also has its advance locked out. FAST recommends the use of this rotor to help prevent spark scatter that could create interference with their ECU. The rotor is a perfect replacement for the original rotor on my 8356. There is only one problem - the lock down screw and washer will get loose and allow the position of the adjustable center to jump out of position. This happened to me, and I caught it before any damage occurred. The actual screw that loosened does not have a tight thread fit, but I promptly secured it back into proper position using Loctite Red (high strength). Adjustment: Set the engine timing to zero at the balancer, be sure to lock your distributor in the number one firing position, then back the engine up to roughly 30 BTDC - then align the center pointer to a mark on the distributor that aligns with the number one cap ignition wire position. Lock the screw down, using Loctite, and you will have the rotor in close phase - at least for a FAST EZ-EFI 2.0 controlling the timing. ...read more
