I am going 404, open rpm, max 2.6" (66mm) turbo at this time. I pull in classes from 6500 to 7500.
It's no secret making a 6000 class with 404/466 block is tough with a Deere. As Lewis mentioned further down on the thread here, using the 329/359 is a better option for weight. I haven't ever used them as yet. Scott Beckett (Beckett Machine) in Ohio could probably point you in the righ

Yes that's the tractor pictured. Not a decube. I ran a unique setup here in Ontario for about 12 years that was turbocharged gas (race fuel), draw through carburetor system (before turbo). Rule at the time was not to exceed 400 ci and no decubing (is now a 410 ci class). It was an original 4010 diesel block that was factory at 380 ci......we bumped it to about 393. It was a cheap way to get

Only problem with 362 is they are only 4 main bearing bottom end vs 7 on diesel blocks. If girdled they may be durable - I've never tried. Short stroke would turn high rpm though.....

30 series 404 have 1 - 5/8" pins. Same stroke as 466. Can't see why they won't work for you.

When it comes to weight on tires.......who says you have to run 30.5's? Give it a try on 24.5's and see what happens.......they are "under" the limits.
Sounds like an interesting concept.

4" x 1/4" as the basic start. The section the engine is bolted to has a full section of 1/2" flat bar welded on the inside for extra strength (mostly for engine mount bolts). From there forward has 1/4" flat welded on to make it a box. The axle is channel with the flat bar back for a full box as well, and it pivots.

Either the 7810 or 7820........ both are good choices. People will argue for and against each. The 7820 pushes the turbo towards the very rear of the hood. Sometimes makes the exhaust a challenge to route.

First time attending this year.....we went Sunday, stayed for the whole show....9 hours! Too bad the Unlimited Mod class had such a tough time, but a great day overall. What a diverse line up of vehicles when you watch the whole show. Hats off to the Langford New Oregon Fire Dept for a well run event. We will be back again next year!!

Which series engine you use is a personal choice to a degree.....certainly nothing wrong with the 300 series if you do your research. It is certainly a fair challenge to get a 400 series in a 6000 class and have a reasonable amount of movable weight without compromising structure. Some have done it with varying degrees of success. I am challenged at 6500 with a 400 series engine, but will admit I

That's a reasonable plan. There are also many trying the 300 series engines as well. Much lighter overall which will help your cause making class weight. Those parts and the associated knowledge are not as popular, but still can be done.
Those older gas engines only have 4 mains.....which is less than ideal for the application. You can use a 362 gas head on a 404 block though ('69 an

Just to clarify, I think some are missing the wording of the rule on when a V8 can be used. It has to be from an OE two wheel drive model.

Sorry, I honestly can't answer that. If you have both types casting number, then cc the chamber with water and find out. Same for ports. If any head had "better" flow and/or smaller chamber, i would guess it would likely be the later model ('69 and later).

By casting number they are essentially the very same head....I can't honestly say that one is better than the other (haven't studied them that closely).
These fit 4010 gas (302 CI) and early 4020 gas (341 CI). These were used up to 1969/serial #201000. Also found on 105 combine gas engines (341 CI).These are referred to as the "wide" block. The top of the block and the head physical

LOL!!! How'd I know this would quickly turn into a 4020/466 conversation.
For the record, a 4010 is a fair bit lighter than a 4020, and this is why they are targeted for light classes. Those who want to use a 4020 rear will have an even tougher time getting to weight. Also Deere made a 404 that is ideal for this class.....not everybody goes 466 out of the box.

Dick, there's a time and place for lighter weight, but you can't paint all classes with the same brush.
......twood makes some very reasonable points concerning the weight of a given class. When you build for it and then it gets changed, it a real pain to butcher what you've made, not to mention the cost. I'm all for being light as long as it's a reasonable number.....

Go with external brakes and save yourselves alot of pain. If you are running internals with brake fluid, you are experiencing a large amount of drag and may not even know it. Also the response is significantly slower once the O rings have swelled. I know its a large expense to go external but when I switched in 2008, we have zero issues since. We went with Engler calipers and am thrilled with the

No rpm limit. Mine's not a screamer, usually see somewhere around 4600-4800 on launch. Depending on track type it's about 3800-4400 down track. This engine likes to lug a fair bit.
