The new year ushered in bigger, more powerful engines, new specialty Supercars, and a plethora of Ponycars. One of the bright spots was the ‘70 LS6 CHEVELLE – MAGNUM FORCE FROM MOTOWN!
In many ways, 1970 was the storm before the calm. The war in Southeast Asia continued casting a pall over a much-divided country and thinning the ranks of young enthusiasts. Carmakers’ racing budgets were being drastically cut and engineering resources reassigned to prepare for restrictive emissions and safety legislation. And Ponycar sales had been plummeting and would register new lows at the end of the model year.
Yet, Motown launched its most aggressive ever portfolio of power. With the industry working on two-to-three-year product development cycles, there was no stopping the performance products scheduled to go public. Chevy’s maximum Musclecar was the 454/450 LS6 Chevelle Super Sport.
General Motors finally dropped its 400-inch engine displacement limit for midsize cars. The Chevelle SS454 championed the assault with an optional 454/450, giving the LS6 Chevelle pavement-pounding power. Few cars, other than massaged Mopar Street Hemis and Buick 455-inch Stage I Skylarks, could hold their own against the popular Chevelle SS. All three cars, especially when tuned and fitted with headers, were capable of delivering low-to-mid-13s at 105-107 mph terminal speeds.
For those who wanted more power and head-turning appeal than Chevrolet offered on SS454 Chevelles, there was Baldwin-Motion. The Baldwin, LI, NY partnership between Baldwin Chevrolet and Joel Rosen’s Motion Performance generated Phase III 454 LS6 Chevelles, lead photo, Steve Calamusa’s Chevelle; above, Adam Tuckman’s Chevelle, with as much horsepower as the buyer wanted. Plus, unique custom appointments not available on new Chevelles at other dealerships.
