I am tired of watching all of the red and green tractors walk away with the antique classes. Mainly what I am talking about are Ms, 720,730 deeres, oliver 77s,88s,and 4 cylinder 99s.
I have thought about building a dc, but I want to get a little desert sunset paint into the scheme of things. Right now I am thinking aobut building one out of a 400 or a 800 COM. I can build either a gas or a diesel it doesn't matter.
My question is which one is going to be the most competitive? I think that I can bore the blocks out to 504 sleeves and pistons which would equal 336 cubes. Basically an 870 engine. Is this going to be Give me your thoughts.

Both tractors are good pullers, I've used both for farm work. The 400 would be the better puller because it does not have the caseomatic. The 400 diesels had a 251cid that ran at 1500 rpm, the 400 super diesels had a 267cid motor. The early 800s 1957-1959 have a 267 also that motor runs at 1800 rpm,the late 800s had a 301cid motor that ran at 1900 rpms, the same motor was also in the 830s. The late 800s and all the 830s had an inline pump, while the early 800s and all the 400s had a rotary pump. I've seen 400 case gas tractors spank any deere or farmall with just minor head work. Even stock the case will run circles around in the field the deere but the farmalls put p a good fight. My suggestion is build up a 400 diesel with a 301 using the rotary pump for a stock look, slightly port and polish the heads and balance the motor, turn up the pump and enjoy.

Paul,
How do you tell which 800 has a 301 engine?
Does the fuel pump have a different tag on it. I have an early 800 with the hole in the nosecone for the radiator cap. I also have a later 800 with the inline pump. I do not know what the serial numbers are right off. What is the easiest way to tell if it is a 301, without tearing it down? Thanks Jake

The 800s with an inline pump are the onse with the 301.

Watch out for the rule on year models allowed. The 800 com started with 1958 year model. My dad has both a 400 and 800. The 400s make good pullers

Also some rules regulate Rpm's and an 800 COM has higher rated rpm than 700 or 400 not sure but 1900 v. 1650
