The mag pickup MSDs (or other) are very reliable, and are less of a concern than HEI units. All are stable to RPMs most here will never see.

The HEIs wide spread terminals are a good thing, helps prevent crossfire/arc. That is especially a good thing once you start using CD boxes with higher spark. They do make the wide setup for MSD dizzies if you want that, but the regular cap design has ridges that help almost as well. I have not noticed any arc witness marks with them (as long as the parts are fresh & clean). Space is a premium, especially with 3x2/2x4 setups.

HEI unit quality is a factor for HEIs, and weights as well as matching weights can get dicey (on OE points setups too). You can skip right past all those drawbacks if you lockout a dizzy (any kind) and use a programmable MSD (or other) unit.

I can see using an OE unit if you are trying to stay original or for a 'look', but makes no sense to be to use one on a performance app. And try finding a good performance cap for an OE points dizzy. The few out there are just as expensive as any other performance cap, if not more. Cheap caps with a CD box are eaten very quickly. Or even just a good coil. Same with rotors.

Just an fyi and for others reading, those really nice and heavy msd caps you can readily buy with female terminals fit the points distributors. I can still also purchase the nice accel caps.

Yes, and are about $55+ without rotor. The 'Streetfire' ones for same money get you the rotor too, but aren't as nice as the regular ones.

I haven't checked on the Accel ones in a long time, but suspect they are about the same price.

Everything is expensive these days so that's pretty much the norm now.

The Echlin Heavy Duty cap with brass terminals and a tan, Heavy Phenolic plastic is $28.00 at any NAPA store. The similar high quality rotor is around $13.00 . Echlin heavy duty points are also available at NAPA. Not sure of cost. Echlin used to make all that stuff for Accel. With Holley buying Accel, who knows where the stuff is made now? Have to assume China.
