HEI distributor and TPI

Can I convert my old HEI distributor to work with a TPI setup. I've noticed that some TPI's have HEI distributors while most have external coil setups.

I imagine its possible to rebuild your current dist using the correct pickup coil, and module that will plug into the ESC used on the early TPI's (later Speed density computers got rid of the ESC). That said, I think it would be cheaper and far easier to just buy a complete TPI distributor that has the proper module and plug in harness already on there.

I will be using a SD ECU (90-92). Can this be ran with a TPI HEI?

How do the distributors differ (physically/visually) between the ESC and non-ESC distributors?

Can I use the cap/rotor/coil assembly from my old distributor with a TPI HEI? I recently upgraded my HEI with all MSD components.

I also have a new TPI module and main distributor body with PU.

For the price of new distributor, personally I wouldn't cut any corners with a cheap rebuild. Especially trying to convert an older HEI to have late model computer control.

You can get a MSD knock-off from Procomp Electronics for $90. I bought one for use in my Camaro using a Holley C950 ECM. It uses the late model, small cap, remote coil HEI style distributor. This will plug into your SD (90'-92') 7730 ECM harness. The Procomp distributor pictured below is a nice billet piece and comes with cap and rotor.

Get it at Fastengineparts.com



I use an MSD #8207 E-coil mounted to my firewall, but if you are retrofitting a TPI system, get a stock or MSD coil and mount it in the stock TPI location.



Fastengineparts.com also sells a nice, economical holddown tab. If my memory serves me correct, it was less than $10 with a stainless stud/nut.



Best of luck, Ed www.edgesz28.com
