The 470 that I'm running right now has the std port 240 heads and the power peak is at 6500 rpm. So I'd say that is just about perfect for a budget bracket or street/strip type of engine. A car can be set up to run low 10's or high 9's with a 6500 rpm shift point without having to break the bank.

Some 4.56 gears with a normal tire size puts you across the line at 120 to 130 mph. 6500 rpm works just fine with moderate priced valve train parts so you don't have to spend a fortune there and you can build a short block with off the shelf parts to turn 6500.
