The Stovebolt Site Forums The Shop Area General Truck Talk Who uses their truck as a truck?

Who knew that having valves open all the way like they're supposed to would have such a positive effect on the performance of this vehicle?

Hahaha!

The truck has noticeably better acceleration. It was no slouch before but it's measurable now. And I did not even push the truck to get to those speeds. Whereas prior to the valve adjustment and repair of the rocker arms and shaft, it would make it to 55 and 60 comfortably and it was a stretch to make it to 65.

So obviously my first sentence was tongue in cheek but I'm amazed by this old truck. I also noticed that the RPM increased without me messing with the carburetor.

I assume because it's running so much more efficiently. I do believe it was running rich in the past due to soot in the tailpipe and on the garage floor.

I actually expect to see a measurable improvement in fuel economy. It was getting about 11 to 13 prior to all of this work.

I turned the idle back down to 600 it had climbed to 800 on its own.

And let not your hearts be troubled. I'm not driving around regularly at 70 miles an hour on the interstate. I just took it out after turning the idle down to see how it was running.

Definitely driving it to work tomorrow, though.
