6030/619 cubic inch?

I'm not picking on 6030's because they are a great tractor and I hope to own one next year.It will just be to play with and not pull.No,it wont have a 619.

The run what you brung theory will ruin pulling quicker than anything if there are no limits.As the saying goes there is no replacement for displacement.Whats wrong with running heads up on cubic inches that most colors of tractors can reach easily?This should have been done years ago before everyone built so big.

If say you can pull a 6030 JD at 800+ cubes why would I want to build a IH having to start at 466 and go to 640 at the most.Keeping a block in one piece at 640 is hard to do.

Why would I want to build a D-21 AC starting at 426 cubes and only be able to build to 585 cubes?Why wont they let me run a N-7 Gleaner combine engine thats 516 cubes to start with?

Why would I want to build a 456 Ford and not be able to build to much over 500 cubes.I have heard of a few 600 cube Fords??

A Case is 504 to start with but I'm not sure how big you can take them.I know some are 585.The boys in Wisconsin can make them run.

A MM is 585 but how many do you see pulling?Its hard to keep a crank in one.

The big reason for the unreal engine limits to start with were the 636 Cat and 640 Perkins V-8's.However,it seems like less and less people are pulling these all the time.

If I were pulling a JD I'd love the high cubic inch limits.If I were pulling any other color I wouldnt because I cant reach those limits.I'm at a severe disadvantage to start with no matter how deep my wallet is.What if the tables were turned and all JD had was a 466 and IH had a 619?

We need more color in pulling,not just a Green and Red parade.You sure hear alot of comments about that any more.

Lets hear more opinions.

Almost any color could easily reach 540 in SF.For a so called starter class 640 is way too big.619's should never be allowed in SF.Use the 466 or 531.

No,I really dont think IH's should be allowed steel blocks when others dont have them avaiable.I can see why pullers want to run them as they get tired of splitting blocks open.A local IH pro stock split a block open right at the end of the season and is quitting pulling.

This 504 on LP could run with anyone in the U.S.In Sept 1969 we watched him get 2nd place out of 31 at the 1969 M&W Pull World championship pull at LaPlata,MO.He was flying when he sheared an axle key and came up 8 ft short of a 1206.

Bill had to pull against V-12 Allisons,318 Detroit powered JD's,a twin turbo 220 AC,1206 IH with a 573 V-8 diesel,and others.

I never got to see Leroy Mason pull the "Down N Dirty" 766 in person but got to see him on TV alot.Didnt he win 29 of 32 hooks one year in the ATPA light SS class.Just a great running tractor but Leroy got pretty upset when the diesels were given a weight advantage over the alkys.

I'm a big fan of the Hulls two alky MM pullers.Have seen both of them pull quite a few times.

I love the alky pulling tractors but I can see the frustration of trying to pull a diesel against them in the same class.What the answer is I really dont know.I'm afraid pulling has some tough times ahead of it.

I've heard it said that Brent Long could build a OHC diesel that would run with the alky burners but it wouldnt be legal.

I have lots of pulling pictures from the late 60's-early 70's.I and my brother once pulled a 12,000 lb 856 IH SS in the early 70's.sure had alot of fun.

This was in the good old days of pulling.You worked the tractor in the field all spring,put the pulling parts on and pulled all summer,took the pulling parts back off,and worked it in the field all fall.

We probably made all of 350-400 horses but were competitive with most every one else back then.Mostly pulled against other IH's,AC's,and a few JD's.

Next year will make 40 years that I have been around pulling.

I had some friends that ran a 1456 at 250 in the field with an intercooler on it.
