HISTORY
In 1967 certain car dealers across America had reputations for building special production
cars with their own twist. These were new cars with dealer installed special additions and
modifications done to them. Some other notable Dealers were: Yenko Chevrolet in Canonsburg, PA,
Berger Chevrolet in Grand Rapids Michigan, Nickey Chevrolet in Chicago and of course
Dana Chevrolet in South Gate, California. Along with Baldwin-Motion cars.
The main man behind Baldwin-Motion cars is a gentleman named Joel Rosen and he is
probably the only person that truly knows how many and which cars were actually produced.
He made these Super HotRods from 1966 to 1974 when they were closed by EPA
from breaking EPA rules. But during that time they produced somewhere around 300 to 500
dealership modified cars in several body styles: Chevelle's, Novas, Camaros, Impala/Biscaynes.
Chevy II and Corvettes. Joel Rosen, of Motion Performance started building supercars in 1966,
and by 1968 he was the #2 producer of specialty performance vehicles, behind the more
famous #1 Ford Shelby GT and Cobra operation.
Except for Joel Rosen’s personal Demo cars that were sold periodically, all Baldwin-Motion
vehicles were custom built to order and powered by big-block engines displacing up to 482 cubic
inches, with horsepower to over 500. A small number of modified, dual-four-barrel Z/30 small-block
‘Green Meanie’ Camaros were built for sports car enthusiasts. Unlike some Chevrolet dealers
marketing specialty cars at the time, Baldwin-Motion never re-badged a single factory COPO 427
Camaro or Chevelle.
All of the Baldwin-Motion cars produced and sold used the same serial number the car
came with from Chevrolet. Unlike Ford Shelby who re-serial numbered all of their models
before selling them to the general public. So all Baldwin-Motion cars are considered
to be "conversion cars" like YENKO Camaros.
All Baldwin-Motion PHASE III (the most modified) cars were sold with this Guarantee:
"Each car is guaranteed to turn 11.50 1/4 miles times at over 120 mph with a M/P (Modified
Production) licensed driver on an NHRA or AHRA sanctioned track."
They were known to be "reliable & streetable" and able to run these times right off the showroom
floor. For example, the warranty on the SS-427 Camaro was 90 days or 4000 miles on the
powertrain and 24 months/24000 miles on the rest of the car - excluding all speed options.
There was no warranty on any engine that was fitted with "internal engine modifications",
such as a camshaft and high rev-kit.
