What do y'all do for throttle linkage on these cars?
(1949-54 Chevys with non-Stovebolt motors in 'em???)
I repaired the broken hinge on my stock pedal, then sat there trying to figure out a way to make it work with a v-block engine. I came up with something that looks like it will work okay, but I can't believe that everyone else does it THAT way!
What I did, was to start by sawing the little "ball" end and a small shoulder section off of the tip of the original steel throttle rod. The original rod was like 1/2" thick and weighed a ton...I drilled and tapped the ball stud to fit onto a 1/4" steel rod then set it aside.
Then, I took the little "L" shaped cast bellcrank and it's mounting stud thingy off of the 216 block and cleaned 'em up a bit. After holding it every which way and working it while looking under the hood of the car, I figured out a way to make it work.
I made up a 90 degree bracket and bolted it to the angled downward slope of the firewall on the engine side. The stud thingy bolts to that bracket, and the "L" shaped bellcrank is now hooked to a 1/4" rod that goes through the firewall and has the ball stud screwed onto the end to mate up with the stock, hinged pedal. The bellcrank converts the back and forth motion of the pedal into an up and down action. A rod traveling up the firewall to another bell crank set-up will work either a cable or a rod hooked to the carb.
The pedal travels maybe an inch and a half to two inches from where the "idle" position would be to "floored". I wasn't sure that this would be enough travel, but after paying attention to how the pedal in my daily driver worked last night, I realized that I only move the pedal maybe a quarter to a half inch in normal driving.
(Although that car has a "hanging" gas pedal that you operate with the tip of your foot while resting your heel on the floor, and the Chevy has a hinged pedal that you can operate with the bulk of your foot while resting your heel on the floor near the base, if that makes a difference?)
Just kinda curious as to how most of you 49-54 Chev guys worked out the throttle linkage and gas pedals in your cars...I can't believe that everyone does it the way that I did!!!
