If you're running a intercooler, put a heat exchanger in the bottom of the ice box and run your return fuel though it.

What ratio area is he wanting to be in? Knowing that would make his question easier to answer. There was 4 or 5 ring and pinion ratios, and two different range sets. Knowing if he wants to be close to 4th, 5th, 6th, ect would make things easier to answer.

I agree with the sled comment. Hiring another sled for one class at many pulls isn't going to work out well.
Considering that most big sleds can work with a 3500lb antique, I'd think one of these compacts at 2500-3000 and a bigger tire would probably work out on a big sled.

If I'm figuring it right, that's about 1300 lbs? Seems like going heavier would make them easier to handle. Que Blah Blah blah driver skill, everyone likes to see tractors actually make a decent pass.

You'll make more power with a 354 with .4 pistons than you will with a 372 with those pistons due to bowl design.
Only .4 blocks had piston coolers, use the rods out of a non-.4 turbo engine. They have a 1.500 wristpin which you'll need for .4 pistons, and they're gun drilled completely to the top with a bushing machined to channel oil around it and cool the bottom of the pisto

This may be hard to believe and all, but with a 6.7 crank you'd have to bore it to the same size as a 6.7 to get it to 410 (6.7) displacement. That block won't like being bored .200 over.

As wide open as the rules seem to be, honestly 500hp is on the low end of things with a 250ci engine, on methanol and efi, which appears to be legal. This sounds even more interesting and fun all the time.
Seriously. My first thought would be a smallblock V8 knocked back to 250, though something from the rice burner world would probably be the way to go. With the aftermar

sfd823 where do you pull? Is de-cubing allowed in your club? If it was I think you would have a hard time proving that a guy didn't build a 414 at 410 and then it got "cleaned up" as you say to 414.
I pull in Ohio. Decubing is not permitted on diesels with the rules we run.

You bring that combo to one of our pulls, and you'll be pushing it back on the trailer and going home.
The 1% rule has and always will be for wear, and for cleaning up the cylinders during rebuild. It's not to sneak a bigger engine in a set of rules that were written to keep them out of that engine configuration. See the engine configuration written for that series of engine.

#1 I have no interest in a 470 diesel.
#2 I wouldn’t use a 4 valve head. .
#3 I wouldn’t use commonrail injection.
Hundreds of thousands of dollars have been poured into CR injection in the truck world, and it still hasn’t proven to have a significant advantage over a p pump except for the classes limited to a small charger.
4 valve heads generally aren’t a game changer. More isn’t

I'd be fine with "recast" heads as long as that head can be bolted on a stock engine, all stock valvetrain, injectors, manifolds, and accessories fit the head, and it can be used in a stock application to some extent.
If we're stirring up chit, I personally think OEM 4 valve heads and commonrail injection on the diesels should be permitted.

I had thoughts of a spark plug Detroit at one time. There was a club that ran naturally aspirated alcohol tractors. Up to 410 cube ran 20" hitch, over 410 was 18" 4 cylinder tractors was given a extra 1000 pounds of weight. My thought was to bore and stroke as close to 410 as possible, run a blower, the taller hitch, and have a extra 1000 lbs.

While I agree with your thinking on a track machine, I would advise against picking a engine that would simply be deemed illegal by a petty official with a chip on his shoulder.
Give it time, Fendt and/or CAT will have the V12 Sisu in a row crop wheel tractor, then things will get interesting.

The semi changes are going to do the opposite of what they're supposed to do. They're going to cost more money to change gearing, and re-learn suspension. The proposed changes would be great to save driveline, but that's not what they're aiming to do. Every truck is going to run a higher gear, and work the engine just as hard as they do now, just with faster wheelspeed.
