Well, it seems that we can all agree that there is a problem with fairly hot tractors running in the stock classes.
Where to draw the line between hot and stock is another discussion.
I wasn't really asking for rule sugestions, as I already have a plan in place for our pull.
I was just making an observation.
As I see it, there are 2 choices for a stock pull:
1. Have a horsepower limit and dyno every tractor.
2. Allow unlimited horsepower and deal with it in another way. (Most of us agree that a speed limit is the prefered way to do this)
So my thought is either way, why not allow bolt in replacement parts or complete engines.
Back to the money thing: a guy can take a farmall m, keep the stock block, head, and all other parts, and have a 130hp or better tractor while staying completely stock on the outside and passing a stock tractor tech inspection. Just takes a lot of money. If this is ok at a stock pull, then why not allow the 310 oliver, and the 403, or even the 605 mini?
A repower is cheaper than a custom big cube stroker. Why make the rules to suit the wealthy and keep out only the repower motors and parts?
A true horsepower limit really is the only way to ensure true stock tractors, but most clubs don't want to deal with this kind of work. And let's face it, if you ban all the modified tractors, there will be no pullers left.
I am not trying to say anybody else should change their pull or their rules. Just making my opinion. I like the Tunica style of rules regarding engines and parts. I think is actually is a little more fair.
