I am telling you that if you work a 460 on up thru the 856 gas on the 87 you will seeze that engine . like i said workingit in like pullen the plow that was made for the tractor or running a chopper or even a grinder mixer OR even blowen a load of silage up the pipe . And you will never hear a ping out of it it will miss a couple beats and just plum slow down and stop and will not start again till she cools down . Now i don't know about you but myself i will run what i know works and keeps me from twisten wrenches . Sop here again when you have worked on as many as i have and have seen what is done inside the engine then you can tell me . AND also for you information the car and light trucks of the sixtys thru 1971 were all in the 9.1 -11 to 1 compression ratio It was seventy two when they started cutting back on the cars but on the tractors they did not do that they just stopped maken them in gas The 766 was the last gas tractor for I H and they did not start rollen back the octane till the late seventys and 80's . As i was still doing work on somer of the older performance cars and that is about when we started have problems with the 10.5 and 11 to 1 compression ratio's . SO it is like this if you were closer i would say just bring your tractor on over and we will fill yours with the 87 put the plow on it and turn you lose and if ya made the end of the field before she locked up i would be totaly supprised. I fought a 460 that lived on a manure spreader and hauled one load twice a day , it would do fine going down hill on the field but it would not pull back up and would just slow down and lock up had to set for fifteen min. then it would maybe make it back up the rest of the way , never a ping out of it he was another like you ya don't need that high priced gas well oneday she did not restart and it was hauled or i should say towed as the guy did not want to pay me 25 buck to haul it. When i pulled the head off all six were scored pistons junk sleeves scrap . HE went and bouth the parts as here again he was sure that i was maken to much on my parts . Built the motor and told him that he needed to up his grade of gas . Nope i ain't ah doing that told him flat out that when it took a dump it was his baby was not two days and he was back the tractor had a noise pulled the head and 4 of the six were scored .Fixed it and told him again this time he took my advice and switched gas it is still doing the same job everyday but now it will go both ways on the fields with a load in soft ground . So you run what you think is best and let the rest decide as it is getting to the point that i am getting to where i plum don't care if ya scrap out your engine . As i said before i am not the one asken what is wrong with my tractor and how to fix then as i know how .
