67 BB firewall pic W/O transistor ignition (balast resistor location)

[Domenic T.]

I bought my car in 1971 and it was wrecked. The left front glass was toast. I still have the original wireing harness and there isn't a harness for the transistor ignition. I may have removed it waaay back then and re-wrapped the harness but I doubt it. I am trying to get all as it is supposed to be. Could you order a 435 BB without transistor ignition? I plan to stay with points but don't know if my balast resistor is in the proper location.
Hunted thru the AIM and looked for pics in the manual but nothing. just trying to save a few hours looking after wasting a few.

Dom, The L71 required K66 TI as a mandatory option.

Rich,
Thanks,
I do have a connector near the distributor with 3 wires. I believe( orange), (green w/blk) and a (black). I did turn the connector back and heat shrink it to the 3 wires.
Does anyone know the exact location of the ballast resistor on the fire wall? I would like to make sure mine is correct?

Dom, There is a dimple there. Just left of the firewall fastener in below pic. But if your car was a L71, do NOT drill it out for the screw. All '67's had the dimple and only got drilled for the non K66 cars. At the end of the line they sprayed sealant on everything, including that dimple and all rubber plugs, grommets, etc.

Rich,
Thanks for the pic that was what I needed. one more thing? those wires in the pic, those are the ones I have that are not being used. What are they for. didn't find them in the schematic?

Dom - those two wires (red, green) run down the firewall to the transmission, at the end of those two wires is a connector which attaches to the connector of the Backup Light Switch (which is bolted to the trans driver's side)

Right Don, thanks for jumpin' in.

Dom, More pics if it helps. This '67 engine bay is quite original.(not wiper motor finish though) Found other pics of the dimple. Is there a hole there on yours? Again, if no hole, STOP.

If you have this clip with the recessed hex head screw under the left female latch, it's a indication that at time of build it had K66. It was added for the TI harness. The location varies +/- a few inches as I've witnessed on many.
Is it there on yours? I'm still a bit confused if your car is/was a 435HP.

Rich,
I,m going to the shop and look for the clip. When I bought the 67, it was a few years old and was going to be parted out. It had the tri power and had headers on it. It, as I said was wrecked and I was told that it was a 435. I bought it without the engine & trans and put a CE engine in it and the solid lifter cam. That was years ago. the CE is a late 67 block. I checked all the other suspension and rear axle and they were correct.
NOW I really hope that it was not the 435 because in 1971 I worked as a mechanic at a Chevy dealership and I added Factory air because the dealer said that my car was not available with A/C.
The pics are wonderful. Rich, about the 3 wires in your other pic, The orange, black, and the green with a black stripe? Were those fot the TI?

Rich,
Yes, I do have that clip, I thought that was for the positive battery cable with A/C cars.

Re: 67 BB firewall pic W/O transistor ignition (balast resistor location)

No, TI was 2 White, Black, Pink, Green coming up to the distributor/coil area.

"orange, black, and the green with a black stripe" sounds like the blower motor harness. These?

edit. 2 Blacks, no green w/blk stripe here. Org is ACC power, which goes to the Radio Condenser then the motor.

Re: 67 BB firewall pic W/O transistor ignition (balast resistor location)

Don,
Thanks, need to get my eyes checked. I see the wires going to the trans. The wires I thought they were, were the orange, black and green W/blk stripe. I now think those wires I had in question went to my old heater only wires. I added the A/C harness that I think eliminated the wires.
Thanks for the help.

okay, then your car likely had TI. There will be 3 holes in the left inner skirt forward section for the TI Module. That is if that is still intact from the accident and didn't get changed. Also a hole for the Module ground wire in the Radiator support to the left and below the Horn Relay(looking from the front).

Again, don't drill out the hole for a ballast.....Ever! Mount it elsewhere on the firewall, like one of the harness clip screws, etc.

Rich,
Core support and fender well replaced back in 71 when I repaired the front end. Also OPPs, drilled the hole back in the 70's and mounted the resistor.
Back then we didn't know better.
I'm dragging out the frame off restoration and am down to chrome, interior, and correct radiator fan. More time spent on research than hands on. I used a 18" from my other vette and need the 17 1/2" for proper shroud clearence. You know the story.
