Is a cool running powerful 426 Possible?

My 220 will be getting the same setup and a front mount air/air intercooler

Finally got rid of the garden hose that was running to the ic

this one could be one of the odd ones that has cam gear slipped of something odd like that. Trust us all when we say, that isn't normal for a 426 to act like that lol! That must be one hot 7000 lol! 

You have one sick 220 if a 130hp 7000 will "handle" it.  Btw, a 220 is rated at 136.

Our D21 35 years ago made 150hp 200rpm under factory rated rpm.
We've run every brand under they sun and never had a complaint in the hp department with allis.

I'm in Georgetown Ky, But the farm is in Lancaster ky.  th HX35 was originally intended for a 6.5 GM(no laughing please) to go in a 2 ton Chevy that had a 366.  Projects like that had to be shelved after our Dad died.  I'm going to get one for the 220 but I'm worried its a little too big.  I know everyone keeps saying its a maintenance problem but we have as follows; 7080, 7060, 220, 190XT, 200, 1950T, 7000 AC (that's gotta be making 130HP, it will handle the 220 any day of the week) G900MM, 1355 Oliver(actually  585 Moline with  DI instead of the old Lanova system), 7600 Ford, 5000 Ford, 3000 Ford, 8N, IH140, two 1466 IH Combines, WD45, (on top of my brothers 24 valve and common rail trucks). All of these run tip top.  I'm not trying to bad mouth the 426, but the 301 is one of the finest running Diesels ever created.  The AC 426's were the only ones that consistently ran hot, with no power down low.  The HX35 was a game changer for the 7080, and I'm hoping it will have the same effect on the others.  For the starting problem, when I talked to Bob King (I think it was him) he told me he never met an Allis that would start without Starting fluid when its cold.

This has certainly been one of the most entertaining threads I've read on here ! What part of KY are you in?

Took a bit of modifying, but worth it.  It's like a different tractor.  At 2550 it is a bit stronger, but its got 80 percent more power at 1600

UPDATE: Its been a long time, but I thought you might want an update...I received a call from my brother yesterday and gave me an update on the 7080 that together we put an HX35 (brand new one) on about a month ago.  His words were "today I drove a turbocharged Allis 426 for the first time". He was so excited.  Before this I kid you not, If it was below 2000 rpm it would not pull itself up a hill.  And it has had 2 new turbo's on it (factory).  Before we did this he said if it got no better he was going to sell and just go get an IH.  For history, we have a 436 in an IH combine that will sing at 2700 rpm, start, and has GOBBS of power. Also due to not dumping loads of fuel without burning it, his EGT's were about 400 degrees cooler so it just sat on the thermostat the whole time. I know everyone is going to say the previous factory turbos were bad, but I asure you they were not. He said at 1600 rpm he could walk up a hill with 14lbs of boost!!!!! No black smoke.  I believe the 7060 and 220 will be getting similar turbos.  Also,  I recently purchase a 4.8l 2000 Silverado with a 5 speed, 246k miles and changed the oil after 3k and it looks like it came out of the jug. (just gotta brag to someone who can appreciate old equipment that runs good, harder than you think!) 

Oh ok we're near Albany

Kinda why the 220 sales dropped so much after the 210 came out? At least that's what I heard some time ago.

I think mines a 70 model. Don't remember ser# and it's up the road.

The difference between a 6 row and 7 row recore was roughly $150 last summer when I had my 8070 recored. Anyone be not willing to do this shouldn’t be pissin n moaning a tractor not staying cool. There are many other factors need to be considered that may also cause tractors to run warm. But for what I do custom baling on hot summer days the extra $150 is money well spent in demanding environments.

Dr Allis we have been round about this before. I don’t understand why you are so against a 7 row of tubes....imo back in the day AC should have had these kids Installled from new. Back in the 80’s when these were new it surly wouldn’t have added more than $75 cost to build an 8070. I I sure as heck wouldn’t have been out buying a tractor strictly by radiator compacity. Ever AC tractor I’ve ever bought was in need of recore. This tells me they may have been undersized from new.

I just picked up a 1975 7040 last year and love it so far. Now all this 426 talk has me a little concerned. It has unknown hours but runs cool and smokes very little.
