69 cutlass S 350 Holley 4BBL

I'm looking for recommendations. I have a 69 Cutlass S convertible with the original 350 and Turbo 350 tranny. I had a Holley 650 4BBL Model 4150 installed with an Edelbrock intake. Tranny was rebuilt but is original. I'm looking for a bracket that I can install on the Holley that will allow me to connect the kickdown cable and the throttle cable. Holley sells one but the slots for the cables are different sizes. Kickdown cable and throttle cable have the same connector size but Holley bracket 20-95 has different size slots. Any ideas?

Many years ago I made this swap. I took the factory bracket and cut off the passenger side end. Since the space between the bolt holes of the carburetor are different on the square bore vs spread bore carbs it wouldn't bolt up. It worked for me, but looking back that is probably not the best idea as it only had one bolt holding it in place. But if you modify a factory bracket you know the cables for the throttle and kickdown would have correct places to clip into. Can you look at your quadrajet bracket to see if you can drill a new hole or weld on an extension to attach it to both rear bolts in the carb to intake studs?

Why not connect the kick down cable to the gas pedal as Olds originally did?

Put the cable thru the firewall, the way it’s suppose to be. No need to buy anything other than the correct cable, no fabrication, less headaches.

If the car is an original TH350, the kickdown cable will already connect through the firewall to the accelerator pedal.

Ah yeah, brain fart on my part. Was it the Chevy that has the kickdown cable attached to the carb Joe?

Confused


I’m confused, so the kickdown cable does not attach here? Do you just attach it to the transmission dipstick and snake it over the rear of the engine and then through the firewall? Then attach it to the accelerator?

Exactly as shown in the factory Chassis Service Manual.

Joe was quicker to located diagrams than I could take pictures! But I'll throw them up here anyway, this is a 1970 Cutlass but your 1969 should be a similar setup. If you don't have the correct gas pedal assembly with two places to attach cables I'll dig one of those out to get some photos. John



Two cables coming through the firewall

The lower one is the kickdown cable from the transmission. The upper is the throttle cable

This is the kickdown cable

Its attached to the passengerside of the transmission and runs up near the distributor cap, then over to the firewall hole.
