The Stovebolt Site Forums The Shop Area Engine Shop 1946 Chevy 1/2Ton - Accelerator Rod from Pedal

Just wanted to ask about other options before cutting and welding my accelerator rod. The pivot point on the side of the my '60 235 engine is about 9 inches from the back of the engine. On my original 216 it is about 12 inches, so a 3 inch difference which makes my accelerator rod too long. I saw on Deve's TechNet that you can drill/tap a hole in the block to move the pivot point forward, but not sure I want to go that route. I've seen pictures of some that have been shortened and welded. I was also wondering about cutting, threading and using one of the couplers to make the rod adjustable? Just looking for other ideas before I go cutting up the rod.

What about using an accelerator rod from a later 235? I don't know if one would fit the hole in the floorboard or otherwise be the correct contour. I may have an extra one laying around you could try.

I sure wish I had known that before i installed my engine. I had to do some serious rigging to make my old stuff work.

Kent, I was looking at some on eBay and noticed the end at the pedal had a round ball. Mine has a flat end that uses a pin and cotter pin to connect to the pedal.

I can’t tell you how many botched up throttle modifications I have needed to fix for people that didn’t work out.
That is why I came up this modification.
It is very easy to do.

Dave, Does that mod put a hole in the block into the coolant gallery?

Yes.

Is the difference a result of the position of the pedals in the AD and Art Deco trucks and /or how far forward or backward the engine sits in the bay?

Here's some info that Dave's link talks about.

utah, the later pedals had a snap in ball and socket joint. that's what you saw on ebay. I think instead of cut and weld, I like your idea of cut and thread and use the coupler you're referring to with nuts to lock next to the coupler. I can see the benefit to tweaking the length until you have it exactly how you like it. you can always weld later if you want.
