Re: Hei?

You need the hei distributor... Pretty much it. I have an hei on my big block. Just make sure all your advances and everything are the same as what you're replacing. Makes the swap easier.

Can use one from any sbc or bbc 1975 & newer--exc. 409 and 348. Run one wire that has full 12 volts when ign. is on and while cranking to "BATT" terminal of dist cap & drive away. Do not use a wire coming from orig. ballast resistor OR one from "R" term. on solenoid.

Re: Hei?

The only dumb question is the one that's not asked. Good luck with the swap, should only take about 20 minutes total. Also, if you've never dug into a motor... Hit up YouTube and search for what you want to do. Tons of genius mechanics on there who show you step by step what to do. But also be weary of the back woods type boys as well.

Re: Hei?

One additional note. You need HEI style plug wires also. The old conventional point style distributor has different ends.

Buy them for a 75 Chevy Pickup with a 350 and you will be good.

Re: Hei?

If my truck was here I might not sound so dumb cause I could look lol but I'm sure the motor is out if an 80's truck would it already be set up this way?

It could be. The person that put the newer engine in may have used the HEI distributor. I would have.

Not just the ends, I believe they need to be at least 8mm (OEM points dist. had 7mm) to handle the increased current of HEI.

Also, re-gap your plugs from .035 to .045.

Re: Hei?

He did alot of goofy things. Didn't wire up the alternator left the wires rolled up sitting on the manifold.

Should have never bought from a mechanic lol. Just like my dad being an electrician and our house was a wire nightmare. This mechanic jimmy rigged his own truck lol
