AC 210

I just got a 1971 AC 210 from a estate sale in michigan, that im thinking of making it in to a puller. This 210 is bone stock off of the farm what can be done to make it pull farm stock 8 and 12 mph. The class rules 2800 RPM, stock looking injection pump, turbocharger inlet bore 2.75" maximum. What can be done to the roosa master, injectors, and turbo and will the clutch and input shaft hold up? Thanks for the help, my uncle has a 7040( 220 rear end) running profarm 466CI, A Pump, with water injection just dont know what can be done to get a stock one to run.

Honestly the first question really is how much do you want to spend on it? There are so many directions to go but it is often based on your budget. You can turn the screw to your stock pump as far as you can and just be happy going pulling. After that it starts to cost. You say stock appearing pump? That can be a grey area by itself. If it was me, I would push to build an ambac pump for it since that came on later 426's factory, and it gives you the best , chance against the red and green show. Some parts of the country may not go for it, but many will. From there, do you want more cubic inch? Few different ways to do that too, how much do you want to spend and how big do you want it? 466, 504, 540, 585, 620? All have been done, each different settup, price too. This is why the first question. I ask when I take on a build is whats your budget? Once I know that, I go from there.

How much cc of fuel can you get from the AmBach M100 pump. Can those pumps run with a 466 John Deere and Case with A pumps? As for as motor work that is no problem dad has a shop and we can do evething is house. Weight class will be from 10,000 to 12500 single tires no cuting cast centers

to bad everybody doesent live in dr allis world but these stuped little clubs are whatmake up the good grassroot pulling. so that the advice of o.p.s and the other good guys and good hookin

"Stock appearing pump" this is a bull crap rule, I agree. Its also one of those times when you may have to read what the rules don't say. Stock appearing for make and model? Or stock appearing for a farm tractor in general? After all a P or A pump where stock appearing pumps on some tractors, where as a billet Sigma is not right?   The m100 Ambac pumps make good fuel, and hold there output at higher rpms then any roosa is going too. A good 13mm ambac will bump 390-400 cc's, a   15mm big nut ambac will get into the upper 500 cc range, but it as mentioned is a very pricey pump, but an ambac is the best shot you have if they're not going to let everyone play on an equal field.

With the speed limits you're looking to run in, you'll be fine with the Roosa pump. Just not the stock one. I've been building combinations for just this. It really is fun to hear all the fuel cc numbers thrown around. The more the better isn't necessarily true. Same with the turbo. I'd set you up with something a lot smaller than your limit, and when the other tractors choke, yours will keep going. Bigger isn't always better. Our tractor holds it's own against A pumps, and 13mm m100's. I doubt you'd get to run an M100 unless it was an 80X0.  

And, with an A-C, you're already 40 cubes smaller than Green and Red at a minimum.

Input shaft is good up to probably 800 HP or so, depending on your driving habits. New 4 pad clutch disc with a much stronger pressure plate is needed.
