What you and pittsburghracer are talking are apples and oranges. Pro Stock, and most class racing in general is a different animal then bracket race engines. Pro Stock in a 2350 pound car with a full pit team, and a spare engine or two in case they scatter the engine, plus sponsors to pay for it all. Most bracket guys have one engine that needs to last for the whole season, a car that can be well over 3000 pounds, a buddy for a pit crew. High RPM's and light weight come at a cost that a lot of guys can not afford. The easy way to go fast is to put stroked engine in the lightest car you can find, and keep the RPM's down so it will live for a whole season. So, for the pro class stuff you are correct, but for the guys on a budget I would take pittsburghracer's combo.
