Being from MD I'm assuming you're referring to Pit Beef as in Bull on the Beach, Bayside Bull and many, many roadside stands and restaurants throughout the area. I'm not 100% positive on this, but I believe the cut used primarily is the beef shoulder clod. It's cooked over a wood or charcoal fire to an IT of around 135˚ in the center, giving you several levels of doneness throughout. Basically, toss it on the smoker and wait 'til it hits your temp. There is no special recipe, as the majority of the flavor comes from the smoke as opposed to complicated rubs or marinades. I'd shoot for a fairly low temp to avoid drying the outer part of the beef. By the way, how was the Tiki Bar opening this year?
