Just want to thank everybodies input @ the forum, great site! So i have a 360 w/ the 6A and blaster coil, any recomends on plugs? Tried the E3 w/ it and no go, dropped the power, rough idle, engine light. Which autolites or NGK would be best for the 6A?

 

3923 autolite can be found at walmart , gap at .040

 

+1.

autolites are the best for our trucks IMO

 

Some don't have as much like with the Autolites as some here though. Champion Truck Plugs are also thought of as good, and I am running the NGK Iridium IX plugs and I like them.

 

I would think a platinum or iridium would be a good choice.
The MSD's are hard on plugs due to the multiple sparks.
I would go with NGK or Champion and try a slightly cooler premium plug

 

you might check the current flowing to the MSD from the PCM computer

I can remember at least two past posts where a MDS 6a installation resulted in a failed Thyristor inside the PCM computer that drives oem ignition circuit, which required a replacement PCM

other posts have said the distributor cap and rotor have much shorter lives with a MSD attached

 

jason whats the part number for your NGK Iridium IX plugs

 

you gotta upgrade your cap and rotor to a mopar performance one with brass tips to help its life.

its just a fact of life with the msd. it eats plugs and cap and rotors.

it needs 8mm wires as well.

 

I think the proper tach adapter (Accell or other) will prevent that as well as ignition codes.

 

I believe they are part number ZFR6FIX-11.
