Wallace says @ 98MPH, 1.88 60", 13.52 1/4. So you aren't too far off. Closer than a lot of folks.

MPH gives you an idea of horsepower to weight, as long as your gearing is not out of whack. Then you can fill in the blanks of what the potential is.

Plenty of places in a Stocker to free up parasitic losses and make the most of available HP. It's all about the budget.
