Gas peddle issue
Is there any differences in gas peddles on a 71/72 auto /4spd trucks? Its a 71 stick cab. Has a 402 in it , I've changed cables long and short and still not getting a full peddle when mashed to the floor. Truck has oem carpet also. Any info will help before I tweak the peddle

Trucks with the manual throttle dash control have a different pedal. The main concern is correct cable length for the application.

Re: Gas peddle issue
I've tried the long and short. No difference at the peddle. How about carb bracket for the cable, I'm using the one for the 402.

Re: Gas peddle issue
If you're not using the stock carburetor and linkage bracket, your engine is mounted differently, or different engine, then you'll need to modify a throttle cable.
I used this website, and called them to verify the carburetor linkage bracket and firewall ends: https://pioneerautoinc.com/cables/accelerator-cables Maybe you find the exact cable for a stock setup. I installed it into the carburetor linkage and firewall, set the pedal where I wanted it to be, cut the cable, and crimped on a new cable stop. I believe I found the cable stops on Ebay. Good luck. |

Re: Gas peddle issue
I forgot to mention that I shopped for a throttle cable that was slightly longer jacket and cable. I first cut the pedal end of the cable off and removed it from the jacket. I cut the jacket near one of the fittings, then I drilled out the plastic and wire from the fitting. It's best to cut the jacket with a high speed cutting wheel. You could use a plastic epoxy to re-join the jacket to the fitting. I fabricated my own crimper out of two pieces of 1/4" steel. I clamped them together and drilled a hole at the seam slightly smaller than the crimp end, I used another piece of steel clamped to both pieces to hold them together, and then I used a press to do the crimping. There's videos on YouTube that show how other's have done it.

Re: Gas peddle issue
On the carburetor throttle lever, if there is a hole closer to the pivot point to attach the cable, that will move the throttle over a greater range.
