Hope nobody gets offended here but I have access to many if not most of the High HP trucks.
There are three twinned trucks that the box can be tested on and any skepticism put to rest. One LLY and Two LB7's
Ben,
I am away for the next week but I can make some calls and get you two HIGH HP twinned LB7's to test the lock-up box on, if it works as you say it does you'll have two sales and all the doubts will be put to rest. The other truck is in Canada but he would be a great test truck as well.

You need to bring one this weekend with you and save me some shipping. I can test it at oakboro saturday night while you are hunting m-80's.:thumb:
