HEI in 1970 ELCO w/402

Gentleman,
The stock point distributor looks pretty nasty, and should get rebuilt ($175.00) or I can get an HEI for alot cheaper....so I need your help and advise again. will a HEI distributor (Proform, MSD, AC-Delco) fit a 1970 elco w/402 bb, cast iron intake, stock aircleaner (q-jet), cowl hood (no door)? If so, anyone have pictures of their setup?

Re: HEI in 1970 ELCO w/402

depending on how expensive or cheap you want to go there is something. I got a distributor from skip white performance that was about 55-60 bucks and a new set of precut wires to work with the hei for another 50 bucks. It was under 100 bucks shipped to my door. This was about a year and a half ago and has been running great ever since.

I realize the distributor is made overseas but the price was right and it made a world of difference on my engines performance over breaker points





Depends on how bad you want american made stuff and how much money you have.. I'm just saying the cap of this distributor looks very similar to a cap on a mallory.

yeah you have to make a harness from the battery side of the hei cap down to the fuse panel to a "hot" lead with key on. other than that it should a straight drop in.

Re: HEI in 1970 ELCO w/402

the pertronix set-up is nice. I run an hei in my 67ss and you can tell a difference with it. if I had an all original ride I think I would check in to the pertronix though.....

Thats because they copy the design.


I would go with an AC-Delco or the MSD. Even a rebuilt unit from Pep-Boys is better than Pro-Form or any other Chinese distributors. Do a search on this site for Pro-Form. It will save you some money and headaches.

I bought one a few years ago from Summit, I was going to use it for a "test stand type setup, but it ended up sitting for 2+ years... Summit Brand HEI, with cap and 50kV coil, $90...

I ended up adding a Summit CD box (mostly for the rev limiter) and dropping it in my 70, and its been in the car for 3 years, and still runs great (decent mechanical curve and an adjustible vacuum canister). Ran low 12's and spun over 6500 RPM...

Not sure where it was made. Possibly China, but I don't recall seeing any stickers, etc...

It seems that the Summit brands are made in America.

Re: HEI in 1970 ELCO w/402

Hmmm... let me see here for a minute...

Points that wear out and need adjusting along with a seperate coil to mount somewhere...
versus an electronic sensor with no rubbing parts that never needs adjusting and has everything built in...

Yup I would rebuild NOT

I run an HEI in my '68 Elco with a 402. Have to replace the resistance wire from the bulkhead connector up to the distributor. Easy peasy.
