Re: HEI swap on a 73

I just did this this morning. I'll run a pic through photobucket in a second. Just have to run outside.

Basically I just ran a relay with the switched power being the old yellow resistor wire for the coil, the power coming from the constant hot block on the fire wall and the ground being ground. Really super simple and it starts, drives, turns off, and doesn't draw the battery so I think I did good. be right back with a picture. it's a little dirty looking but I was in a hurry because there was more important stuff to do while I had a helper.

Here ya go. Total cost was about $7.00 and it'll get you running without cutting into anything for the time being. Maybe later if you want to tidy things up you could start pulling power from other stuff but personally, mine's just an old truck (and it's a '73 like yours) and looks like it. Not going for fancy, just functional. I wouldn't even have run the HEI except I had to throw another engine in to get it going again and the new one was from '87 and had the HEI coil already and it was easier to wire it in than put the old points distributor on. Hope this helps you.
