AJ's Car of the Day 1970 Chevrolet Chevelle SS454 LS6 Convertible

Car: Chevrolet Chevelle SS454 LS-6 Convertible

Year: 1970

What makes it special: It turned heads and intimidated the competition on the streets in 1970 and it continues to do so 44 years later. To this day there is still nothing like the LS-6 powered Chevelle SS454. The single-year option "Bow-Tie Beast" still has many dreaming of owning one to this day.

What made it famous: In 1970, Chevrolet offered it's exclusive 454 cu in big block V8 as an option on the Chevelle model, and choosing the RPO Z15 SS option got you the standard 454 LS-5 at 360 hp. The LS-6 was a $233.30 upgrade on top of the RPO Z15 upgrade, and was rated at 450 hp. The LS-6 option brought a 4.25-inch bore and a 4,0-inch stroke, specialty heads, solid valve lifters, a high performance camshaft, a Holley 4-barrel carburetor, and 11.25:1 compression. It could be mated to a Muncie M-22 Rock Crusher close ratio 4-speed manual transmission with a heavy duty clutch, and a 12-bolt Posi-Traction rear end.

Why I would want one: It's without a doubt in the top 3 of the top 10 of any muscle car fan. It's combination of power and good looks is irresistible, and it remains one of the most collectible cars to this day. The fact that it's a convertible only sweetens the deal. I cannot deny that I would cherish owning one of these.

Fun fact: Factory standard Chevelle SS 454 LS-6 models were reported to be able to accelerate from 0 to 60 mph in just over 6 seconds, and even today they continue to break the 12 and 13 second barrier on the quarter mile.
