Gleaner 226 Not A Replacement Engine

Been having a discussion with some friends about rules that have been bent over the years and this is one. I ran across a thread in another forum last year and a fellow had brought up this topic. Truthfully I agree and don't understand when it come to the rules in most pulling circuits when it says must retain stock engine or "factory replacement" that the Gleaner 226 is far from either of these. I do however understand the want for more power but per the term replacement parts for the tractor must duplicate original then how is this allowed?? All the ones I've seen the frames have to be notched amonst other parts having to be modified. One guy says that Allis sold these engines because they quit making the originals but everything Ive ever read and researched says otherwise. Replacement blocks had no stamp code at all on them is what a old timer from the dealer told me. Keeping to the rules what is yall's thoughts on this...Not looking for a argument just input from whats been discussed throughout your years of pulling.

Our local rules allow any engine, of the same number of cylinders,  of the same manufacturer that bolts in with out any modifications to the tractor.  If you run into a problem take all the inside parts out of the G226 and put them into the W226 block as the others do. Sadly most restrictive rules have been made by owners of green or red tractors that are poor loosers.

Well I have a Super C farmall and was told that if I put a 153 engine out of a combine I would be cheating. ...I know this is something that has been happening for a long time but as appearance goes your right you can swap out internals but you can't change the block code or the castings so how is this legal for one and not any of the rest. I actually have a sheet on a replacement block for these tractors and it says the casting will be the same without the tractor code stamp,wc,wd,45 and then the propane. I'm just curious as to what the real advantage to the Z code block.

Matt, you should look up Cliff Stughart and his Farmall C he pulls. He goes from 2700 up to 4000 lb class with it and does very well. I have no idea what is in it, but it is very healthy.

A 460 in 4500? About 5500lb class.is where they fit in here

@Charlie175 they pull 460's down in 3500 around here. It's all in how much you wanna spend. Put a 150hp 301 in it and let'r eat.We personaly don't have one that pulls in 3500 but we do 4000 cut tire classes. He's probably 200 hp and is pretty much unstoppable. Our rules are very vague when you get past super farm it's pretty much run what ya brung.LOL
My 45 right now weighs 3540 with me on it and I'm 250. I would like to pull 3500 but my tires don't hook until I can get at least 500 lb on the back of it. I have 14.9x34 michelin radials on a 16" rim. It sucks but they're all I can do right now. I've got a nice set of 16.9x30s but I can't find any rims. Those radials are very heavy with a radial tube in them. I could probably lose 200 lb or close to it getting the 30's on it and then Im hoping to pull second gear.
