Re: [DML] Horsepower vs Torque

[Michael T Twigger <marktwigger@xxxxxxxx>]

Don't forget that torque in a smaller engine has max 
torque at a much higher rpm. While bigger engines such as a 350 has 
peak torque as low at 2000rpm. Which is much more useful. It means
less shifting, and more useable power for everyday use.
