The Stovebolt Site Forums The Shop Area Engine Shop Mallory, Pertronix, Langdon or??

Yes, I think most any 12V coil of 45-55000V will work with the HEI's. It isn't necessary to match the vendors to have a good unit.

Mallory cost way too much and you can get a just as good result at lower cost so there won't be as many of them used. Not sure they even offer a unit for a 235 era engine.

Pertronix is the most popular and is lowest cost so naturally it "could" have a little bit higher failure rate but that is pure conjecture and unproven. I've heard those stories about carrying old points crap in your glovebox for years. Just a lot of BS in my opinion. Hell, anything can break.

As for the "Langdons doesn't look original" thing it seems to me the only visible difference is the absence of the flip tabs to hold the cap on. The twist screw tabs are better anyhow. So if that is your deciding criteria then fix your old point dizzy and keep on smiling.
