20r powered allis-chalmers
 

Hey guys I have purchaced/inherited a old tractor that at some point has gotten a 20r and a 4spd trans so my question is how do I get more torque out of this old,yota I have plenty gear reduction but would be nice bot to be in 1st gear in both transmissions ya know :coffee:

Others may have better ideas, but I'm going to go ahead and say that "it is what it is". Other than a tuneup, there's really not much worth doing to it. It's a great engine, and wasn't meant for more than it was built for.

put in a 22r and torquer cam, or if you have the budget, a 2.6L stroker from lce.
Oh, and I'd really like to see some pics!

torque and a toyota 4 cylinder don't belong in the same sentence

It's all relative. For an engine of it's era (early 70's) and displacement they actually are pretty torquey. Peak numbers aren't jaw-dropping but making peak torque under 3k RPM isn't too shabby.

Nobody else interested in seeing this thing???
PIC'S PLEASE!!!
