anything to be gained by switching a stock H cam for a stock 300 cam? how about having it reground? running 3 9/16 firecraters 300head stock stroke looking for 50+hp thanks JYD

The SuperH-350 cam helps with low end torque. In the lugging rpms it is a more steady torque curve. For 50 hp, you should have the Super H-350 head, cam, intake and carb, tuned to the engine, 3-9/16 bore, 169ci, will make 48-50hp at 175 psi of compression, your cyl head can be shaved a bit to gain the 175 psi compression, and when you set the carb up for the compression increase, the hp #s will go up more as well. If you have not done anything to the carb, distributor,or governor yet, let me know, I can tell you how to do it all yourself! ChadS

HEY CHAD , YOU ARE GETTING WORSE THAN DENNY HE CLAIMS 1 HP PER 3.4 CID WITH HIS WORLD FAMOUS 409 WHERE AS YOU ARE SAYING 1 HP PER 3.38 CID . YOU FORGOT TO MENTION TO THE FELLER HE WILL NEED TO PUT A SMALL TURBO ON THAT STOCK 350 TO GET TO 50 HP. I THINK SOME PEOPLE NEED TO TAKE A BREAK FROM ALL THIS DYNO TUNING ENGINES AND MAYBE CALIBRATE THIER DYNOS OR DON'T FORGET TO WEAR THIER GLASSES WHILE READING THE H.P. DIAL. I SEE TOO MANY OF THE NEW PULLERS GET THESE SO CALLED 150 HP TRACTORS TO THE TRACK ONLY TO SEE A GOOD HONEST 100 HP TRACTOR PULL BY THEM . REMEMBER THE DYNO NUMBERS WONT PULL A THING .AND A DYNO OPERATOR CAN MAKE IT READ JUST WHAT YOU WANT IT TO. TIRED OF THE BS, DR

Dr, hows it going? Its kinda like the 200 hp M farmall claims right? I hear ya! and I know exactly what you are saying. I just report the facts my friend. Built quite a few stock cubed, high compression engines. Alot of trial and errors in what we've learned with messing around with tuning. The numbers dont lie too, thats why I challenged them all who had the 200 hp M farmalls to bring them and dyno em, but no takers. Even the big names did not respond, and you and I both know they are on this site. Im not attacking them one bit,, but I belive that you phrase is correct, "bragging 150 hp" cause it will pull like it has 200, and actually 100hp. 50 hp out of a C-169, takes 175 psi of compression. Its not rocket science, its been proved already. I have the engine to prove it. Anyone can twist the numbers, but why??? I have no reason to! Myself, I am proud to announce that the rules are changing for the technology from yesteryear of pulling, farming etc etc! it takes compression to get your power from a low rpm engine, along with the right parts, machine work, and the know how to set them up. Balance is the key to pulling, hp is a good thing to have, I agree, its not all about dyno numbers. Would be happy to show you what you have to do, to get 50 hp, from a C-169-175 displacements.

If 50 horse is possable on a stock 300 as you say super h-300 cam 300 head ,168 cubic inch, well 200-250 horse on a660 cubic farmall m moter, With performance parts is not out of the question ! My .02 cents for what its worth

LOL, Maybe, just maybe. As time goes on, the engines, and their builders learn that something else can be done, to add to what they have already done to thier equipment. For some reason, its never enough. Shoot, 120+ hp was unheard of in an H block till a few of em started showing up and can back it up. But thats built to the hilt, with no deck plate, or what have you. Funny thing about the IH engines vs all the rest, is that they are very easy to improve, bout like the Allis WC-D-17, factory parts evolved as production models, and years got newer. IH, made one heck of a line up for performance parts, maybe they did not see it then when they built them, but ones who have played with them, well they know the combinations it takes to get the unheard of HP, from such small cubic inches. From over the many years of turning wrenches on pullers, Learned one thing about IH. IH 4 cyl engines are tough. And, they love compression to make power. Ive played the what if games before, and tested the questions I had in my mind on what I can do, to make it better. Dyno test, after dyno test, on my own equipment. Customers equipment. Stock parts, to the high dollar stuff. what works and what dont, and why. Just look at the AC tractors, the parts swapping that can be done, and make some good cheap HP, IH,,,,, well, they were just like that, add a bit of technology to what is available now, well, may eat my words about a possible 200 hp at 540 M engine then! Ill leave the Big M powerhouse bragging rights to those who have them, they built, and paid to have it. so let them brag upon them. Me, Ill stick with my specialty, H-350. 100 hp H's are easy to build, and use 90% IH parts doing so. 50 hp is a walk in the park. 200hp is a walk in the park, to those who have built them, the right way. My .02 cents. but Im all in on that one. ChadS

took the head off today how much can you take off before running into clearence problems? going to send it out for a valve job might as well kill 2 birds with 1 stone. what do you run for gas at 175 psi?

JYD, It can be milled .200, if it has never been machined before. Have the head checked for cracks, Measure the head plate thickness at one of the ports, keep it no thinner than .250 thick for a full time puller, and .300 and beyond for a farm/puller. Should not have any problems with clearance with the 300 head, it is relived in the casting inside the compression chamber for the firecrater pistons. 93 octane should be sufficient at 175psi in one of these engines. But try to avoid racing fuel, unless that is what you can only get, or use. These engines love a slower burning fuel, yet potent enough to prevent detnonation. Ethanol is about the best in my opinion, a little bit, goes a long way to help build torque. ChadS

I was looking at your answer about getting 50 hp out of a 169 ci international engine with the 350 heads and 3 9/16 pistons. I have done everything that you mentioned (carb,distributor, and governor). My question is how many rpm are you running your engine when it is producing 50 hp? I would appreciate any help you can give me. I can only get 40 hp with stock rpms. Thank you, Chum

I have a 53 Super H, that pulls div 1 type classes, this tractor, started it all for me in antiuqe tractor pulling, on an NCIATPA pulling track, it is the one to beat in the 3500-4500 farm stock classes. It has firecrater, 3-1/2 bore, it has a 8043DD Early super H cyl head, same casting as the 300-350 heads, but the old H head number, milled .200. no port work. It has a 4 weight governor from the factory, with one of my springs, the Super H-350 camshaft, and the big carb and manifold factory stock on a Super H. Now, This ol Super H is no stranger to the dyno, 15 years of testing and tuning on it, It started out as a 39 hp tractor. Its 45 now, and still more to make more hp. Add a lp head, it would be over 50 hp, at less than 169 cubes. But, we are not working with a lp head. First, how many hours are on your engine? if its less than 100, and not used much, well the rings still may not be seated in, if it has a bit of blowby, then run it on the dyno a bit longer. May still not be broke in. Run a compression test. pull all the plugs out, open the throttle all the way, and crank the engine. Check all 4, and see if there is a difference in the readings. if so, you may need to retorque the head, reset the valve lash, any adjustments to be made to get the peak cyl pressure for that cyl. While you have the plugs out, look at the color, are they black? lite brown? If you can get the main jet to flood the engine when backed out, your fuel could be giving up, if its like 87 or what have ya,, you may need to step up to a better grade gasoline, it depends on your compression test results. at 120psi, you are 35-38 hp. at 150 psi, you are 38-40. At 175, it can vary a bit. Seen this before, cause the cam and head comes into play at 175psi, that is really the starting point for compression, for the IH to make power at the smaller cubic inches. Even though only 25 psi more, it makes a huge difference in how these engines breathe. thats where the late head and cam come into play. The torque wakes up big time, and the improvements can be more clearly noticed. These are very peppy engines when souped up a bit. It takes compression. Have you milled the head? what have you done exactly?? Let me know, or email me, would be happy to help. ChadS

How much compression does you engine have? What carb, cam, and fuel? If you let me know what your compression is, Ill tell you what your engines potential is. AND where to find whats hiding. Happy to help you, email me! If it is under 150psi, you need more. machine work, and a bit more details on how to tune it. I just left the basics,for engine design. First off, when dyno tuning, its not just hooking up the pto to the tractor, and running it, you have to look at the factors, plug color, fuel, compression equal, or close to equal across the boards. Engines I dyno are set up to run 20% over for starters. But at 540, its 1815 engine rpms,,, it takes compression, and the stock 3-9/16 firecraters wont do it alone. Would be glad to talk to you, email me or call me. 574-893-7437 ask for Me, or Earl. Email is best at this time,, been in and out of the shop alot, but will return your email. Would denny do that? LOL! ChadS

SHAVING THE HEAD AND WORKING ON A CARB AND THE DISTRIBUTOR AIN'T GOING TO GET 50 HORSE FROM A STOCK BORE AND STROKE 350 FARMALL. I DON'T CARE WHO TUNES IT. BESIDES THAT SHAVING AN ALREADY WEAK HEAD THAT COMES ON THE FARMALLS IS THE LAST PLACE I WOULD LOOK FOR COMPRESSION. IF YOU TUNE THE DYNO YOU CAN MAKE IT READ 50 HORSE THOUGH . JUST TWEAK IT TOWARD THE 1000 RPM PTO SPEED SIDE AND YOU MIGHT GET 65 OR 70
