Blacktop Posted May 4, 2019 Share Posted May 4, 2019 Got fed up trying to fix my running problems and lack of power so bit the bullet and binned all the junk. Holley 4 barrel, Edelbrock manifold and duraspark distributor fitted with hei module. Got a few bits to tidy up then it’s ready to run. I’ll post some pics later.

Gary Lewis Posted May 4, 2019 Share Posted May 4, 2019 That should do it. Are you fitting the HEI module in the dizzy? I'm curious to see how that's done. Can't wait for the results. Link to comment Share on other sites More sharing options...

No I’ve mounted the hei in a separate housing on the drivers side fender well. Found the wiring loom to be in a terrible state at the back of the engine, bare wires where they had worn right through! I’m surprised it didn’t catch on fire as the fusible link to the ecu was bare! All gone now that the computer and associated wiring has been removed.

Those wires may be the worst I've heard of. Having said that, I did part out a truck once that obviously had a bad oil leak on the driver's side. And when I retrieved the DS-II harness I found out why - it had been trapped under the valve cover! Not only was there a substantial leak, but the insulation on the wires was badly damaged.

I installed a relay harness I found at Rural King. Has relay, all the proper gauge wiring, I am using the original coil wire to trigger the relay. Just finished soldering, and wrapping the harness. Cant wait to fire it it. About heat....on a 300 six the HEI dizzy get PLENTY of air flow from the rad fan. I would not worry about heat in my case. If a factory GM HEI can live, perform and do well at the back of a chevy up agaist a firewall, then an HEI mounted basically directly in front of the fan on a ford will remain better cooled. Six half dozen or another. Dont really matter where you put the module. Put it where you want to. It'll survive just fine. Link to comment Share on other sites More sharing options...

I’ve got the module mounted to an aluminium plate with heat sink paste between. This is then inside an aluminium casing with the relay, and mounted on the plastic inner fender. I will carry a spare module in the glovebox too just in case. I’ll post some pics soon as I can. Alan Link to comment Share on other sites More sharing options...

Alan That is the way Lucas did their "constant energy" ignition, GM 4 pin HEI module in an aluminum heat sink that mounted between the coil bracket and fender on an MG, on the Jag 6s it was on the front of the intake manifold as the coil sat on the front of the head.

I think we discovered that those systems are EXPENSIVE, even in the UK where Alan is. So, he's come up with what is probably an inexpensive, at least by comparison, alternative.

He is using the stock dist. that have vacuum advance what dist. you using to trigger the GM part? Oh you have a v8 so that stock dist. with vacuum advance should work right.
