Thread: Real Dumb Chev. HEI question

Tweet

Okay, some back ground info, i'm currently building a 47 ford sedan delivery as a shop truck, it has a chev. vortech 350,700R4 trans and a ford 9 inch rearend.
My problem is the engine will not start, i have fuel,compression,oil pressure but no spark! the dist. that i was trying to use is a unknown. when looking at a new dist. they all have three wires coming from the dist. housing, was told that they were for a timing module on a computer car.

Will the engine run with out these wires hooked to anything? do i have to use some type of jumper? or do i have to find one with out these wires, no one at the parts store could tell me

Told you in the beginning it was a dumb question, but when you only do chassis and fabrication work, its real easy to be dumb as a rock on something like this.
Any help would be great, Thanks

Not sure if I understand the question. If the dist you have is a HEI, and has three wires coming out of the underside, these should be in a plastic plug. This plug, then plugs into the receptacal that houses the coil.( Plugs in closest to the cap) The three wires are for the coil, one of them is a ground and the other two, go to the coil itself. A fourth heavy wire (hot when the key is on) goes into one of the remaining plugs, (I think it is molded in the cap cover which is which,) the fifth one will be a tach wire, (it provides a pulse for the tach, which then reads it as engine rpm) So I guess the short answer is, yes they have to be hooked up. I have diagrams of this stuff somewhere, the trick will be finding them. If your still stuck, or I understood this all wrong give me a shout, and I'll hunt it up for you. Sniper

Here are a couple of good sites with HEI info:
