can someone give me a diagram or tell me how to wire in an HEI as well as a push button start with a on/off switch for my 64 tempest 326. also by setting it up this way is their anything i will be disconnecting that is crucial to run car? lights?charging?etc? thanks in advance

Doc here,

Do you intend to LEAVE it this way...? or is it just for a test or short period of time?

Push button starter: Run a wire from the battery positive terminal to one side of the push button switch..

The other side of the push button switch will go to the wire that goes to the Neutral safety switch..then from there to the "S" terminal on the starter solenoid. DO NOT DEFEAT THE N/S SWITCH!!

Toggle Ignition: One side of the toggle to the Battery.

The other side of the toggle to the "BATT|" terminal on the HEI...and remove the wire..this will give you engine "RUN" when used in conjunction with the push button.

ANYTHING on the IGN Buss of the fuse panel will be dead if wired this way, as well as engine monitoring and depending on your charging system, state of charge..

IF you tap into the "BATT" wire instead of disconnecting it, your IGN buss will work as before..BUT be advised...

YOU NEED To assure that the switch can handle the current draw..if not use a relay!! The coil alone will draw between 20 and 40 amps..add to that everything on the IGN power buss..is a healthy draw..

IT would be much more simpler to get an aftermarket "Generic" Ignition switch you can get at like auto zombie....then trying to use buttons..cost about $12 bucks..and can handle the draws safely..

what do you mean by remove the wire?

I like pushbutton ignition. My '51 Chevy has it and It's pretty neat to have it, course it is stock that way, and the car is all original. uses a 3 way ign switch. off, ign on, and another off which can be hooked up as an ACC but Chevy never did, and a pushbutton on the oposite side.

Doc here,

The wire at the "BATT" terminal of the cap is a slide in connector..

you only have room for one connector in there..therefore you must remove the "BATT" wire from the cap to install the new..If you parallel it in (cut and strip it) It gives you full functional-ability of the IGN system at the fuse-buss (back feeds into the fuse panel.)

THINK i can get a diagram... kinda confused with the jargon..

Doc here,

It's simple...look on the Cap on the distributer..There will be only one wire that goes to the BATT terminal..It slides into the cap.

You MUST remove that wire / terminal in order to install the new wire from your new switch. (you can not get 2 wires/ terminals in the cap plug) This will give you power every time you turn the toggle on to the coil..

IF you DO NOT unplug that wire and just splice into it..it will turn on the COIL as well as the rest of the fuse panel under the dash..(as it did before on the stock switch.)

ok i think im confusing everyone.. my car has points dist setup now.. so i was asking how to install
1. HEI system
2. push button ignition and on/off switch for ignition.

I think the info you are giving me is for existing hei system which i dont have yet. would it be the same wire?

To install the **STOCK GM**HEI system is simple..

Set the rotor to #1 Plug tower on your existing distributer now, and check the timing marks for line up..

Pull the old one out..install the new one in it's place, you will note as it drops in the rotor will advance slightly, This is because the gears are diagonal cut..so you have to keep pulling it up and setting the rotor back a bit until it is on # 1 plug tower when it seats all the way down..not a bit ahead of it..

Once that is done , replace you cap, and you will note it has two terminals on the left hand side marked "BATT" and "TACH" ..the wire from your ignition goes to the "BATT" terminal..and if you HAVE a TACH, It will plug into the TACH terminal..

NOTE: If you had a ballast resistor / or Ballast wire..it MUST be removed prior to installing the HEI, else, if it DOES run..It will run like crap in a can..The resistor will be located on or near the old coil, is a small box metal box about an inch wide by 3 or so long..has one wire from the ignition..and the other to the old coil +.. The resistor side that goes to the ignition is what you want..

If you have a resistor wire..it will go to the coil + side and be a (usually ) Cotton sleeved wire..cut this wire out and install a new one where it came out to the coil "Batt" terminal..

Why do you need a Toggle switch??

Anyway, it installs between the battery..and the "Batt" Wire going to the coil / Cap on the HEI..(if installing, you don't need to mess with the resistor / resistor wire at all..just tape it off and forget about it.)

thanks i think i got it.. the car is stripped and ill probably race it for a while and the previous owner had the ignition switch out and was having probs, so i figured i would just put a toggle and push button..

Doc here,

12 will work but I'd go 10..just in case additions will be forthcoming in future..and a fudge factor..
