Alright, this is my 2nd favorite car made under Chevrolet and I honestly don't see why PD didn't bother making a premium model of it.

Wikipedia quote:
The LS6 produced a claimed 450 Gross HP in solid-lifter, high-compression, guise. It has been suggested that the LS6 was substantially "under-rated" and actually produced something on the order of 500 horsepower (370 kW) as delivered from the factory. Recent engine dyno tests have proven that the 1970 LS-6 engine makes over 450 hp and 500 lb/ft torque in stock configuration ( stock compression ratio, stock camshaft, stock intake and exhaust manifolds). Super Chevy Magazine conducted a chassis dyno test of a supposed production-line stock 1970 Chevelle and recorded 282 peak HP at the wheels. This test that was not done under SAE standards. The engine was said to be correct but is not confirmed.[11]Current 1/4 mile times and MPH of a 1970 Chevelle equipped with 100% factory stock LS-6 engines and modern tires are turning very low 12 second times (13.07) with trap speeds of 112+ mph.

A very nice classic car. I would be happy to see all the classic muscle cars upgraded to premium.

It is quite unusual to have the power figures understated - in the muscle car era they were normally exaggerated as each company was trying to outdo each other both in engine capacity and advertised power.

The measurement used was SAE Gross with optimised humidity and air pressure, long tube test headers instead of the normal cast iron manifold and no ancillaries connected - e.g. fan belt, water pump. air conditioning, power steering etc.

When Jaguar started selling the E Type (XKE) in the USA they advertised it as having 265 bhp which was greatly exaggerated to keep up with American market expectations.
