So....I'm having a discussion with someone off line. I am told that all the theory about building motors to race has no bearing in cars that require "street motors" in "street cars". They don't use 5000 Stall converters and don't need power in the mid-high RPM ranges.

I am told that a "street motor" makes most of its power between 5500 and tops out at 6000 RPMs and has a ton of torque down low. Sounds more like a tow truck to me.

My CTS has a redline of 7000, and most cars from the factory are redlined at least at 7000.

It is my opinion that TODAY's street motors are at least 7000 RPM motors, that 5500-6000 is antiquated thinking or for tow trucks.

Can you help me define what constitutes a "street motor".

Thanks.
