Guess I'll have to scrounge up a much longer cable to reach all the way around the whole mess. I was thinking about pulling the throttle lever from under instead of over, but the rocker cover is in the way Maybe I will have to fabricate me a new cable mount. Guess I goofed, I've had about 4 different setups on this manifold. Some where along the line I got confused about which direction the carb faced.
I used a 48" Lokar cable and a Spectre bracket slightly modified. Some have used the stock throttle cable and modified bracket and pulled from the bottom with 2" of spacer under the carb to clear the valve cover. But I looked at that and thought the "throw" off the bottom was a bit short so I opted to go the other way and pull off the top. Ended up with a close fit against the heater core housing but it works just fine.
So is that the length I need? I was trying to decide how to measure that somewhat accurately today. Guesstimating that mine is a 2 footer right now. I think that I will spend the money to buy the longer cable, I can use the short one on my '66 Ranchero when I get it up and going again someday.
Now I just have to come up with the design of heating the intake with water. I don't want to use the heated carb spacer, scares me. What if the spacer corrodes through and you injest water before you know it?
Seems to me the coolant would be very slow to warm. I would think getting quickly heated air from around the exhaust manifold via the large flexible tube to the air cleaner is much more efficient. JMO.
The tube from the manifold shuts off after warm up, so you really need both. The coolant maintains the manifold temp.
The stock cable is about 24" but I questimated a 48" and it worked just fine...even shortened the cable a little (not the cable housing) to get the install just right at the carb. You can build a bracket or modify something like a Spectre bracket (a little grinding) to get it to fit where it mounts to the carb base bolt BUT that is with my carb set up. Your's may be a little different...just takes a little adapting and improvising. I suggest staying with a quality cable like the Lokar that way if you get a little tight as I did against the heater housing it will work just fine without binding.
I am going to use my existing bracket, that is why I need the longer cable.
I know you have a different year truck but I was able to reuse my orginal throttle cable and throttle bracket. All I had to do was make one bracket to connect the factory bracket to the offenhauser intake. I made this piece:
I see too that you have the same 300 cubic inch decal on your air cleaner that I have on mine. Using all the orginal throttle cable and throttle bracket mad the swap really easy. I haven't had a problem with it. Your truck might of been different since its a 1969 vs my 1982.
Originally mine had linkage and a bell crank to compensate for the off set carb. It never seemed to work correctly after I put the four bbl on it. So I converted it to cable.
