If you can find m&w pistons for a 201 will bring up comp. quite a bit. Assuming rpm. that most pulls allow, around 18-1900, around 60 is about the best I've got.

Wasn't a 175 gas (226) rated at 60 some HP? So that would be top of the tractor series.

The Combine and Power units were rated higher but that was Flywheel HP

The model 175 gas tractor was rated at 60 HP at the PTO and 67 HP at the flywheel, both at 1800 RPM loaded. I'd guess with a well tuned D-19 style carb, that stock engine could see maybe 73-75 flywheel HP at 1800 RPM, but at 2000 loaded RPM for sure. More compression and good racing gas will just keep adding to those HP numbers.

Thanks for your replies. Now lets go the other way, lets say its only gonna turn 1500-1600 rpm, how can you make this engine lug--torque? I am guessing cam and its timing would be a big part of that, how about compression? I always heard high compression is great for hp, but not torque. I have also heard high compression with good fuel and retard the timing will bring torque. I am trying to figure out if there is any way to get enough power to run 38 inch wheels on my wc in the 4000lb. class. I have seen WDs with 45 crank and 4.125 flat tops struggle to do it. I know wd is geared lower than wc, so I wonder if I can do it with out building a "bigger enginge".

Camshaft timing advance would help with "lug".   These flywheel HP specs are from a standard D-17 gasoline @ 1400 rpm.....52.0 HP @ 1300 rpm......48.2 HP @ 1200 rpm......44.2 HP @ 1100 rpm......40.2 HP @ 1000 rpm........35.7 HP @ 900 rpm........31.4 HP @ 800 rpm...............peak torque was at 1100 rpm with 211 ft lbs.

Compression will help with torque.

Heavier flywheel helps somewhat delay the "stalling" of the engne as the load increases. Doesn't make any more HP, but helps in some situations and surely never hurts.

Has anyone ever put a gas head on some thing like a 226 diesel block ? Just a lame idea.It would have higher compression and have stronger parts in all the bottom end.

No such thing as a 226 diesel block.
