I'm currently running a Mallory 85 series HEI with vacuum advance. I'm running into some issues with a misfire under load around 2700+ RPM. I think my HEI is starting to fail. Parts to rebuild with cap, rotor, pickup, and coil, are not much less than buying a new one.

My question is what distributors are you guys running, doesn't necessarily have to be an HEI. Don't need any external boxes.

I have the MSD pro-billet ready to run distributor on my convertible...it runs great

I second that! MSD ready to run with a blaster coil.

Eric, what generation is the engine in your Cutlass? I was trying to look at Summit but I don't know much about you're engine except make and displacement. Seemed like the MSD ready to run units were about $250 depending on generation etc.

It's a 72, but I don't think I need all that hi tech BS right now. I was actually thinking on going back to points. The HEI has been a ok since I fired it up, granted it was used when I got it, but like I said above, I can buy a brandy new shiney one for what the parts cost.

The curve seems ok, I can set it at 18 initial and it max's out at 34.

Ok, got an MSD Streetfire for the time being. Set at 34* @ 3500 Rpm, which put my initial @ 16. Back in the saddle again, no pinging or surging with the 17* vacuum advance can.

Checked over my old Mallory 85 and it seems it may be good after all, apparently the last time I had the cap off, it seems that it is a little deformed and did not seat all the way. Everything seemed to check ok, so I believe that was my problem. Some time down the road, I'll get a new cap and rotor clean it up and run it as a spare.

Davis Unified Ignitions (D.U.I.) makes a nice replacement HEI.
