We built and ran a 88 oliver for 7 years and tried awhole bunch of everything with the engine. Our last engine was just shy of 400HP with the stock 4 main block and we were spinning it 5500rpms in 4th gear and depending what sled we were pulling sometimes 5th gear. As far as the block and crank, definately balance the rotating assembly and build a girdle to go against the main caps for extra support. Another problem that these blocks have is the main caps move around especially at higher rpms so I would also recommend finding a way to pin them so they don't move. Also if your going to pin the caps, go ahead and use ARP studs and then have the block aline honed. The 88 blocks are also hard on camshafts when spinning excessive rpms, there is alot of moving around going on in the crankcase and what happens is the backlash between the crank gear and the cam gear disappears at high rpms and breaks the cam right behind the first cam journal. I could keep going on and on but those are some of the major things that we found out thru trial and error. Good luck

Finally someone else that likes RPM's! I ran a Oliver 77 gas with a 770 motor. Everything inside was stock but just had been overhauled we ran it at 3700 RPM. We pulled every other weekend 9 months out of the year for 2 and a half years and had No problems. We sold it and now have a 880 Diesel that were running at 3850. Its had some work but like the 77 the engine has never been balanced. I've pulled it a year with no problems also. However I have plans to have the engine balanced over the winter. I would recomend having it done if your going to run serious R's.

Your running that much r.p.m. out of a stock motor with no problems? I've got an 880 diesel was wondering what it would take. Do you have a charger on it? Did you have the head flowed? I've got a roosa master pump on mine it really woke the thing up. Could I run an 8000 pound class and keep up? My motor has about 250 hours on a complete overhaul. What can she take? THANKS!!

As far as 8000 thats up to you. Around here I dont run above 7500 because their is a naturally aspriated Case 1070, several 4010's and 4020's, a Ford 9000, a Oliver 1850, and one 1066 that can get in the 7500. Are you going to keep up with them No! But somewhere your pulling against other like size tractors I would think so.

To be on the safe side I wouldnt take her to much past 3500. We have had some head work, injectors, and pump done to flow more air or fuel. It has 3 7/8X4 and is considerably a stock tractor. Both tractors we've had No problems with anything coming apart. We just check every once in a while to make sure things are good and tight. I have an 880 Diesel Naturally Aspirated but it has super 88 sheet metal and a S88 serial tag.

say oak farms, I have A 77 with big pistons&cam and want more rpm's what is the trick? I put an extra spring on the gov. linkage that gets me 2200 r's , is it the vacume advance on the distributer?

thanks for any hints, kevin in wisc.

Well this is the way were doing it, you might find a better way of doing but though, The spring on the throttle linkage you take and pull it together with wire. Their are other ways you could find to do it. But basically you pull that spring together tight and that will let it open up more but your governor probably wont work quite as well and the throttle will be a little harder to hold down. It takes several trys to get your R's where you want them but once you do it seems to work pretty good. Like I said their are probably better ways someone can find to constrict the spring but thats how we've done it.
