Manual Choke Info Needed - The 1947 - Present Chevrolet & GMC Truck Message Board Network

**special-K** · 10-23-2011, 05:04 PM

I'm putting a manual choke in my '71 C/30 tow truck. I'm hoping someone could give me a picture of where the choke comes through the firewall on a post-68* truck with manual choke so I can drill the whole as close to where the factory did. Thanks in advance

*67/68 location would be just as good. Maybe they're the same place?

i got a gauge cluster out of a 72 c50 and put it in my 72 k20 and it has a fact location for a manual choke under the wiper switch. and there is a hole in the dash when you remove the gauge panel that i suppose was is there due to intercangability.

I will look on our '71 grain truck tomorrow.

I don't remember what year it was but someone here had a pictue of a firewall with every hole labeled but I can't locate it. Maybe someone else has it.

**special-K** · 10-23-2011, 08:22 PM

Thanks you all. That picture with the holes labeled would be one I'd save. Only trucks with manual choke will have the hole. Pondscum,yes there is a place on every dash to the right side of the cluster for choke and/or throttle. I measured from the center of the wiper switch hole to find the center of the lower hole and drilled out a 1" hole in the cluster. I have the cable installed and now need to drill a hole through the firewall for the cable to pass through to the carb on the right side. I guess I could figure a good line to follow and just drill a hole where it seems best,but I'd rather put the hole as close as possible to the factory as I can so it looks original.

Tim here's a pic of my 68. Only I can't remember if that's the choke cable or speedo cable. Maybe this pic will jog somebody else's memory.

PanelDeland · 10-23-2011, 09:26 PM

On my 68 it's nearly directly in front of the knob.I realize that you're looking for later model though.Maybe the firewall hole is in the same spot?

**special-K** · 10-24-2011, 06:46 AM

Fishingred,thanks for that picture. When you showed the first picture it made me wonder if you had a 6cyl. I think they run a different route than a V8. I realize now I should have added that I need the location for a V8.

On a 67/68 a truck came with manual choke unless the SPID shows the auto choke option.

I'm willing to bet they're in the same place. The holes in the dash are about 2 5/16" different vertically. It wouldn't make any difference.

I figure a V8 choke cable would have come though in the recess behind the motor to cross over to the passenger side.

My truck has an Edelbrock spread-bore intake & Quadrajet. The intake has no well for choke. And,I just kinda like the added mechanical feature in such a truck.

68gmsee · 10-24-2011, 08:24 AM

Just in case they're in the same location, here's a pic of the cable location for my 68 GMC that I found this morning.

I was wondering the same thing about the 6cyl vs 8cyl after Panel said his came out directly in front of the knob.

I can get pix of my 68 but i dont know if it was originally a electric or manual choke truck

it originally had a sbc but not on the spid so i assume 307

fishingjred73 · 10-23-2011, 10:22 PM

Found another pic. It's the choke cable you can see it in this pic when you enlarge it.

**special-K** · 10-24-2011, 09:58 PM

Yeah,I'm sure now that V8s and I6s had different routing. Makes sense since the cable goes to opposite sides of the engine. I'd still like to see a picture of a V8 choke cable coming through the firewall.

This one is a 1971 C5500 with a 351E

This one is a 1971 C6500 with a 366

The rubber coated one is the choke cable. The other one is the throttle cable.

As you can see, they both come through the same spot.
