If you don't have a good fan with a shroud around the outside and an air gap between the fan you can have problems. What is hot? blowing out radiator or temp on gauge?
if gauge temp, could be bad gauge. If blows out could be weak cap. If radiator has bubbles when cap is off looking into radiator, thats sign of leaking head gasket.If you have a thermostat in the engine that can be a problem.

We commonly get asked how our transmissions look with the bigger gears.
Also can we build it without the TA housing for modified and classes that don't require a bell housing.
If you go with our big input shaft this is what they look like.
WE also do M transmissions with spline bottom shafts and bearing supports. Also one piece input shafts for those as well as with universal yoke for v8

the 5.75" stroke will fit in with some grinding on the side of the block, using stock rods dt 466 pistons cut to fit.that will get you around 505 cid.
the crank i am referring to is a 466 crank stroked. the newer crank i haven't ever done.

You need to find some friends with tables to help guide you along unless you have lots of experience.
They call it a leaning curve! All I can say is thanks to you tube for online education. This is a bultear table. they are built really well for the price. Once you have figured it out, you will wonder how you got along with out it!. good luck.

Going to say the 478 will work but looks like the 8.3 wont get in. The limit is 479 using nyprofarm rules as a guide. They have a good class with this limit, so lets stick with this. If we add cid then these tractor cant go to all the other pulls. You will see this class running at pulls where top from each area come for championship pull, so the rules need to run close. Keep me posted with your

There is no answer to that question. If you ask which performs better stock on stock engine you may get an answer. And most common answer is 426 is better. And that answer could be argued between owners of each.
The total combination makes the difference in the heads. Running them is the real way to know. Depending on which valves you use and if one is ported different then it will run differen

I have had a few discussions and The engine mounted solid, should mean no movement between rear to the engine. Engine is to be mounted solid with no ability to move separate from rear of tractor. We will not require cast iron. The engine needs to be in stock location. I think that we are going to come up with a measurement to give all tractors equal chance. We will have a minimum and max distance

There is a ton of interest in this class and sounds like we will have to set up the east coast show down for this year. That is if that name isn't takin' for another pull. Maybe this is the making

Spark plug tractors can run in the same class.The diesel tractor will be separate from alcohol tractors places will be for each fuel. I don't have any experience running the alcohol tractor to compare and keep fair, that's why I asked for replies to this post. It seems to be the opinion from calls I have gotten to keep them separate and then that will eliminate the need for compensating

Didn't list safety rules, to spec. I agree with you. And I wouldn't have a class without all safety requirements met.
General Safety Rules
1) All vehicles required to have an SFI clutch/flywheel blanket or SFI clutch can assembly. Blanket to be 17 inches wide, 6 strap, fastened front and back to chassis.
NO cast iron clutch or flywheel components.

Interstate has a buy out rule on the turbo and the intention is good. That would help keep it where no one wants to spend 5000 on a turbo and sell it for 1500. The bad news is what if a guy bought a turbo just the same as all the rest but it just seems to work better. That would be a bummer..

I have read about 6 sets of rules for clubs in several states. The key to this class is the light weight, 18.4 tires and limit on the turbo. From all that combined sticking with diesel only will be a plus. After many discussions today it seems that even if we allowed 470 cid with 3 inch turbo that the bigger engine and more power only means burning the tires off with limited weight to move and l

We are about 45 minutes from Binghamton, NY.
Should we keep 470 cid limit or will we have more interest and tractors to fit a 410 rule?
I am going to say the tire limit after talking and reading other club rules should be 18.4-38 OR 20.8-34.
I like the 24.5 tires but to keep the weight down and traction it sounds like we need to stay with the smaller tires.
The general consensus is that wi

This class is only a work in progress. I will build any tractor to run with whatever but we locally don't have this class. Our goal is the exact opposite we want to increase tractor numbers.

wny allows inter/after coolers, also they are a 24.5 tire limit. We have been looking at rules from many clubs and I see a lot of similarity to what we are in need of.Is it possible to adjust the rules across the nation so you can pull in mo or ny or ky with the same rules? It would be nice if this class which seems to be popular across the nation. But the problem is who wants to make the change
