1948 farmall c bone stock flat pistons and all.
Yesterday the tractor proved to be vastly under powered even for our long chain stock tractor pulls. It has a magneto. Is there a way to give it more juice? Such as advancing the mag? Simple stuff. T
 
You could also go with a overbore kit with the pop up pistons and look for a 140 head and do a good valve job on the head and some minor carb work.
It might come close to same amount as a motor swap.
A distributor might help a little because you can adjust the timing. A mag usually jumps right to 35 degrees advance.
 

I'm looking to have this tractor perform up to par with stockish super C's. Right now it loses power in 3500# class.
 
I don't know if thet still make them but IH had at one time a oversize Fire Crater piston & sleave kit. We put one in a 1947 B and it make a big differance ( never lacks for power)
 

I believe for our club to be considered "stock" you have to have the from factory block. So a different engine isn't gonna fly. I think the 123 pistons are acceptable because that is what most all of them run anyways.
 

Probably can pull the sleeves. Cleanup the bore and install over size high compression pistons?
Have the cam and followers re-ground.
Port match the head to the manifolds. End the rough edges out of the valve bowls. Have a machine shop install over size valves with a three angle valve job.
Distributer is a good idea.
