Junk the cam and go to a 350 camshaft. Best one your gonna find for the best power. What kind of pulling are you doing with the H?? That engine, even at 40 hp, is good for tractors that have more of a stock hitch setup. The closer you move the hook point to the rear axle, the more power it takes to keep moving. Try to get a #23 for the venturi,,,, that will give you the best low end power, if your running racing fuel, go back to a good pump gas, that stuff does not belong in a low rpm engine, period!! The timing likes to be retarded on these engine, tune it in onthe dyno if you can, while its at 500 instead of 540 pto,, since your rpms are in the lugging range, thats the rpm range you need to focus on to tune it. That cam has to go, it was doomed from the start,,,, sorry, thats the reality of it,,, your not running a large stroker that requires anything beyond the best upgraded parts from the factory,, and even then, custom cams may hinder the engine instead of helping. Only better cam option would be just a step above the specs of the 350 cam,,, still,, 40 hp aint bad for a H with an overbore kit,,,, So,, think of the hook point and maybe move it back farther away from the axle, that may help it without changing parts,,,, Let us know what style pulling you do,,, weight classes,,, tire size,,, etc etc,,,, More info coming soon!
