When you go for a test drive, what impresses you about the engineered ride quality?
The acceleration, the continuity of speed over changing terrain, the way the mirrors and dash do not shake, the smooth power at all throttle positions, the longevity of the service parts, the lack of rattles.
Do some research if you never used a .6 + lift cam. Roller or 454 means nothing. That is 180 degrees from a street driver.
4 speeds are fine not a problem with a race car. Why wouldnt it operate at 3000 rpm. Are you imagining its just going to die?
