The most enjoyable part of an engine is from idle on. Why shouldn't the power curve match?

 The only old car I've been driving is my '68 Camaro. It starts to make power around 4,000rpm then it peaks and starts to dip around 7,500. This is great if you keep the needle up that high, but if not it doesn't really give you the neck-back pull.

The engine built for my project Mustang (Project Street Fighter) behaves much differently. I have only seen it on the dyno, and compared the printouts to the those from the Camaro's engine dyno day. The difference is extreme. While the Camaro doesn't make 400 horsepower until around 4,700 rpm, the wicked Smeding-built 427 Windsor started it's pull at 2,500 rpm and I never saw a number below 423.

This makes me really excited to feel the difference between high-rpm power and low-rpm torque.
