Did they also have stock heads, intake, valve lift, flat tappet lifters, bore, stroke?

Also you don't run those combos now, why change if it was so easy? The tried and true formula for bracket racing is a 4bbl carb, transbrake, glide, aftermarket engine, big tires and methanol. 0 of that is common or legal in stock lol (unless it came with the right carb from the factory, all combos vary).

You may have found consistency and success with it in the past, but you can't argue it is the most effective way to bracket race. Otherwise 99% of accomplished bracket racers are doing it wrong lol.
