Msd distributor advance stop bushings
Can anyone tell me the sizes of the advance stop bushings on an msd distributor ? I can’t tell what color it is because it’s a little rusty. Also , what spark plugs would you use on a 454 with B&m 250’s? Got this old project boat almost ready,,,, |
My bushings are .430 |
Assuming BBC rect port heads, I would run AC MR41T plugs.
|
Thanks for the reply, I will try them. Any idea on the distributor bushings? I took my msd apart yesterday,trying to figure out the timing curve. |
Also, yes they are bbc rectangle heads, were mercury 400,s , now mabey 550 h.p.? |
The kit should have all the specs https://www.summitracing.com/parts/msd-8464

Thank you Griff, I’m going to look at it, I checked my plugs, they are NGK # 7 |
