I should have posted my latest blurb on this site instead of the ih discussion board I guess, but Im trying to do the exact same thing with my 39 H> Just today I found a complete c-169 motor with carb, and manifold for about 250 bucks. I told the guy to save it for me while I try to get all this info together. I,m all for the most economical route we can. Chad we are listening.

Migraine, if you have a C-169 hunted up, you are all set if it is any good! If the sleeves are still decent, bore them out to 3-5/8, run the C-175 kit. Or install new sleeves from the 350! The 169 has the good cyl head, cam, and it is the big bore block. (if you decide to bore it out) ChadS

using M pistons with the stock rods wont work. The compression height on the piston is way to tall. Either get smaller rods (probably have to be custom) or get custom made pistons. Arias pistons in california will be more than happy to hook you up. But i also belive that there is a 3 13/16 piston out of a 560 lp or something like that is just what the doctor ordered. Correct wrist pin size and compression height and everything. But very hard to find.

As far as a stock stroke engine, with stock rods, pistons from the 350 C-175 engines would be about the best bet. You would need the newer cyl head for these pistons due to them being firecraters. You can use stock rods up to a 5-3/4 stroker H engine, but git out your grinder, and hang on!! Lots of cutting in that one. Just think of how many hp you are looking for, what kind of class are you wanting to pull? Low gear, 2nd gear, ?? 3500, 4000, 4500, 5000lbs?? For a smaller stroker engne that dont require major block grinding is 5 inches of stroke, stock rods, (you have to grind them down for clearence) and then for pistons,,, well that is a whole new ballgame! at 5inches of stroke in the H,s you can now use the IH 6 cyl pistons wit hthe compression height of 2.024. there is alot of different bore sizes ranging from 3-9/16 up to 3-13/16. The 6cyl wrist pins are much smaller than the H, but you build a brass bushing for the rod, to do 2 things,, 1 is to adapt the smaller wrist pin tothe rod, and 2 is to help set the compression height on the piston and rod. I usually remachine the 6 cyl piston to the pattern of the H compression chamber, and pick up alot more compression. You are able to move the wrist pin location up, or down in the H rod wrist pin bore, just depends on where you measure where the wrist pin bore location in the brass bushing, on the H rod. economy route is the 350 engine kit inthe H block. with all the good parts, (newer cyl head, Super H -350 cam, Super H-350 manifold, and carb) 50hp with a bit of carb, cyl head, and tuning.

Hi Chad

Will a 300 UTILITY PISTON W/ ROD SET C-169 ENGINE fix in a 1939 H ? I'm planning on using this tractor , I may pull for fun at local fair.

Going to have to put a new sleeve set in it. If I use a 300 flat top piston and a 300 head , or would it be better to use a H head ground down?

Thanks!! Teddy

Do you already have the 300 pistons? I think you can put the 300 rod on the H crank, you just have to use the H rod bearing with the 300 rod. Id have to double check that info, but I am pretty sure you can. If you have a 300 head for your H, you can do 2 options if you are budget minded. If your H still has the sleeves in the block, bore it out to 3-9/16 and install a super H C-164 kit in the H block. You can then get firecrater pistons, which make pretty decent compression. Or go out to the C-175 engine kit that is 3-5/8 bore. Just remove the sleeves, bore the block. The problem with the 3-5/8 kit in the H block here is the sleeve flange left over in the block deck. You can either have rings made to fill in this gap, or you can run without it, and use a 350 head gasket. The 350 head gaskets have a much bigger fire ring diameter, and can seal on the block around the gap. Like I said, check the 300 rod on the H crank issue out to be sure,, I am sure the difference was the bearing thickness, ChadS

Yes I have 300 flat top pistons on the way. They are old stock new item. Size is to be 3.5 . I was thinking they would work with a standard H head I have with harden seat in it all ready. But have a 300 head I can switch from an other H. Have a new manifold ( h-300)and was going to look for a bigger Carb. Was not going to go too big plan on using this tractor. Thanks!! Teddy

Allow me to add to this,, The Super H had 2 bore sizes, 3-1/2 bore, and 3-9/16 bore. The 3.5 bore had the large H wrist pins, the 3-9/16 bore pistons had the small wrist pin. ChadS
