    85551 is rated 4.8 out of 5 by 14.
    Rated 5 out of 5 by from Msd enough said Installed this and works beautifully.. I love the tune ability of the timing curve with a quick spring change
    Date published: 2019-09-01
    Rated 5 out of 5 by from Works good Msd always makes good products, I just wish instead of having to cut the quick release j clamps for the cap, that it would come with just the screws installed so you have a more secure cap.

    Hi which msd distributor will work the best for a chevy V8 454 that will talk happily with a fit tech 30012 1200hp system ? thanks

    Asked by: dodg1e
    This would work, but you will need an ignition box to use with this distributor.

    I am using a comp cam roller cam that requires a melonized iron distributor gear. Is the gear that comes installed on part# 121-85551 msd distributor compatible with my cam?

    Asked by: Elky468
    Thank you for your question. MSD 85551 Gear would have to be changed for your cam. http://www.jegs.com/i/MSD-Ignition/121/8561/10002/-1 That is the Melonized gear.
