Quick ? about I6's and HEI wiring - The 1947 - Present Chevrolet & GMC Truck Message Board Network

**CPNE** · 11-05-2004, 04:56 PM

I have an HEI from a 77 Nova that I'm installing on my 250 six. It has the external coil (not integrated into cap). My question is how do I wire it as it does not have a spade marked battery on the coil as on the V8 version. In short:

Which spade terminal on the coil (as you face the block from the RH side) does the 12v lead go to? Is it the rear left spade or rear right spade? The rear right has a plastic tab on it that aligns the harness from the HEI pick up, so the standard connector won't slde down on it. Also, does this need to be grounded in any special way?

Your using an HEI?! So it must have been stock then?

Jeff call me tomorrow toll free if nobody answers on the board, I have divorced coils on a couple of 292's at the shop.

Thanks Ed, I got it wired and it runs great!

VTBlazer, touche

Here is a pic of the engine. It has PS and will have the correct air cleaner assembly for the booster clearance too

Mechanic's hand soap like Goop or Gojo will clean those plug wires to to look like new.

I was happy it ran at this point, but thanks for the tip. There's a lot left to do
