It does - when you use baby heads on big cubic inches....
The Dart Pro 1 - 180cc heads are going to kill HP at higher rpms. But that was the way we planned the motor. It's a HOT ROD motor... I wanted big TQ down low in the band -- and was willing to toss the big bragging HP numbers in order to get there.
My Nomad weighs 4023 pounds - runs a 700r4 - and 3:70 gears... Tranny shifts about 5500 rpms... I have smallish tires in the rear. It burns rubber but won't set any 60' times! LOL
I wanted a "smoothish" running and torquey motor. The cubes and small heads (fast air flow) - give me the torque - but the small heads are going to kill the HP numbers. Here's something to look at:
RPMS TQ / HP
3286 478.3 / 299.3
4000 513.4 / 391.0
4600 550.0 / 481.7
4900 541.5 / 505.2
5100 527.6 / 512.3
5500 500.4 / 524.0
5900 455.4 / 511.6
6200 419.3 / 495.0
