Need HEI
Permalink  
 


In short: looking for a good used HEI distributor or a recommendation of a good new one. 

the advance weight pins in my swap meet HEI are very wobbly and one actually pulled right out with the advance plate. Been squatter tuning a big but can’t quite beat it and also have a lot of bucking when idling in gear at 850 or so rpm. Was going to change advance springs to see if it helped and one pin just came right out!

If new, was looking at pertronix flamethrower or msd street fire with vac advance. Feel like I’ve read a lot of “not good” on the cheaper, sub-$100 hei’s like the house branded summit or jegs but I’m open to suggestions.

Well I just did it and ordered a new pertronix unit with a rev limiter. That feature seems like it’ll be handy for me….

I’ll probably rebuild this distributor and weld the pins to keep as a spare.

New Flamethrower 3 showed up. First impressions are: seems kind of cheap. Mostly just the cap and rotor. Casting seams, etc just show like a cheap import. Internally it looked fine as far as I can tell. I changed out the adjustable vacuum advance for the adjustable I had on the GM HEI because the pertronix one needed about 14” vacuum to even start moving the advance. I flipped the advance stop plate that limits the weight travel as I had read online a lot of them come installed backward, which mine was. Also swapped the gear to work on my roller cam. Tightened up shaft end play too while I had the gear off. The GM unit had .20”. That’s not a typo. The Pertronix had .030” so I used a combination of shims from both units to get .010”. Installed and it fired right up. Haven’t even set timing yet, just stabbed it in about where the old one was, then cranked it up. I’ll play with it over the next couple days to set timing. Oh, also set my rev limiter to 6500 rpm and added a deep groove alternator pulley so I hopefully stop tossing belts. This engine will rev and still make power way past 6500 but I need to stop breaking stuff. 
Forgot to take any pics of the unit.

I’ve never owned a Pertronix product but have read mixed reviews, especially when I had the Scout II. A lot of people say D.U.I. is better but you pay for it also. I hope you have good luck with this one.

I’ve got pertronix in my current cruiser (points eliminator) and have had them before. I had bad luck with a points eliminator years ago but not since. I’ve got the stock module and coil in the glovebox.
