Farmall H mods

[Greasemonkey81]

Hello,
I come to you all humbly and thank you in advance for any advice you may give.
Im restoring my great grandfather's 1941 Farmall H. It was the first tractor on our family farm. It replaced the mules.
I picked up a C175 engine. I'd bought the last 4 Case IH C301 pistons that were stocked. CNH no longer has stock. So I want to bore the block to 3-13/16" for the new C301 pistons. I've been reading that you can use the stock C175 rods with these pistons and the crank will need stroked to 5-3/4". What is the longevity of this settup? Does the block need sleeves or is the cast parent bore ok? Will I need to decompress?

I had one bored to 3 7/8 and just filled the block. I didn't stroke it tho. gm

I'm not a H guy, but stroking it is the way to make big power. So So I would call H A P I at Terrahoute In. and find out the specs of Their H cranks. Or Crank machine
At New Baden Il. Don Carpel. He can make your rods too.
