Baldwin-Motion Phase III Corvettes – Part 1 of 3

From 1967 to 1969, the hottest street Corvette was the 427/435 L71. Not a bad ride for most folks. But Joel Rosen isn’t “most folks.” Rosen owned Motion Performance in Brooklyn, New York in the late ’50s and ’60s, and was having considerable success as a local drag racer-tuner. Read More

The Last Baldwin-Motion Phase III GT Corvette!

On June 3, 1971, Dr. Henry Rollings took delivery of his air-conditioned, 500+ horsepower, 1971 Phase III GT from Joel Rosen at Motion Performance in Baldwin, New York. Power was supplied by a blueprinted and balanced 454 LS6 big block built to LS7 specifications and fitted with a GM high-performance hydraulic cam, open-chamber L88/ZL1 aluminum heads, headers and a Holley four-barrel.

R.I.P. Joel “Mr. Motion” Rosen

On the cover was a bright yellow 427 Corvette, branded, “Baldwin-Motion SS-427 Phase III Corvette”! On top of the standard ’68 big-block hood bulge was a grafted-on ’67 Stinger 427 scoop that totally looked like it belonged there. On the sides of the Stinger hood were badges that read, “SS-427”.

What Happened to the Side Pipes?

It all got me to thinking about those infamous, barking side-pipes that were offered from ‘65 to ‘67, and slightly milder ‘69 side-pipes that made even the 300-HP small-block sound as ominous as a junkyard dog. Two unique designs were offered back then. Beginning in ‘63, as part of the overall Z06 package, was the $37.70 N11 option, the Off Road Exhaust System, which included low-restriction, under the car mufflers and 2-1/2-inch exhaust pipes. This option was available through to ‘68 and was officially listed as “off-road.” (That’s GM-speak for “race track”, is in, racing.) The N14 Side-mount Exhaust System was another animal altogether. The system begins at the end of the exhaust manifold flange with the typical 90-degree bend. But instead of bending towards the back of the car, the bends were directed towards the sides of the car. After a short distance of about 12-inches or so, there was a gentle bend of approximately 118-degrees that leads to a long, straight tube that passed as a “muffler.” The “muffler” portion that ran along the side rocker panel had small crimps that created little internal baffles – and not much baffle at that.

R.I.P. Vette Magazine 1976-2019

In the spring of 1997 I pitched then editor, Richard Lentinello a concept I called, “The Illustrated Corvette Series” as a monthly column. Lentinello liked the idea, but didn’t have an open page for another columnist, so it was, “Thanks, but no thanks”. A week later Lentinello called me to ask if I still wanted to do a column, as one of his other columnist informed him that he could no longer do his column. Of course I said, “Yes!” My plan was to cover every year Corvette in chronological order; so maybe I’d have 50 installments. When Vette magazine was shuttered last December I had completed 275 installments and got a book deal from Car-Tech Books in 2010. Read More
