Aftermarket blocks in Super Stock

With a lot of interest I have followed the discussion in the USA about aftermarket blocks in the Super Stock class.
Let's see:
Some decades ago there was people putting different engines into their tractors. Very quickly they got seperated from the "stock" tractors and the "modified" tractor division was born so the "stock tractor" guys don't get busted off the track and still have a place to run, because they didn't want to put non OEM engines into their tractors.
Then people started to change engines over to methanol again the class got devided into "Alky" and "Diesel" - hurting it's numbers so badly that in a lot of areas on this planet there is not enough tractors to run either one class anymore.
Then we got the component issue, because the tractors would make too much horsepower.
The only thing left "stock" was the engine block and now being able to transfer all the power without having to worry about the driveline anymore, the OEM blocks are now too dangerous to run??
Are we now getting "aftermarket blocks" for exactly the class that was made for people who wanted to keep it the word "STOCK" in their class?
What really amuses me the most though:
There is now engines coming off the assambly line, that you are not allowd to use in Tractor Pulling anymore.
Somehow I think we've totally lost track of things and should try to get back to the original intention of Super Stock Pulling.
In my opinion that is:
Take a stock tractor and modifiy it to the best you can do out of it.
For me that means:
Take the original block, the original head, the original transmission housing and rearend that belongs to that block and leave them all in their original position.
If you want to run a 4-valve head, then live with the new, lighter blocks that come with it.
If you want to run 600 cubes in a strong block, then live with the transmission and head that belong to that engine.
If you want to run methanol, then put some spark plugs into your original head.
If you don't like fooling around with stock parts, then go play with those people who saw the light in the 60s already: The modified pullers!
I'll guarantee you: They don't mind you running a hood!
Ok - this will never happen as we're far beyond the point where this would be possible anymore.
So - how to make the best out of the current situation?
We need:
1) Color on the track
Deere and IH will NEVER EVER give us any sponsor money because we run quite a free advertising program for them anyways. The only ones who have given us money or parts where Valtra, Claas, Landini, Lamboghini, Fiat, MF, Fendt, ...
2) Close competition
3) Stock appereance
4) Stock parts under the hood
Since it's all about agricultural machinery, and we've f...ed up everything else of the original tractor already, why not allow an engine out of an articulated FWD or combine of that company that stays within a given size of let's say 540 cubes? Hey.. it will still be a red, green or blue engine and be A LOT closer to the company than any aftermarket block and it would still be Team JD, CNH, Agco, Landini, Claas or whatever...
