Detroit. Beginning in the late 50s and running through the mid-70s, sports car racing - particularly here in the U.S. - was captivated and dominated by V8-powered machines that barked their intent at race tracks all over the country. Sure, back in those days, SCCA (Sports Car Club of America) events were heavily populated by small-bore sports cars like Austin-Healeys, Triumphs, MGs, Minis, 356 Porsches and many other brands. And there was no question that they provided the backbone of SCCA racing back then. But starting in the late 50s with race-prepared Corvettes, and then fueled by the emergence of the Shelby American Cobra, and on to the USRRC, Trans-Am and Can-Am days, the real action was with the big-bore machines.

I vividly remember seeing the crowds gravitate to the fences when those V8s fired-up on the false grid. They couldn't really help it, because the sound was guttural, menacing and mesmerizing all at once. Standing among those cars on false grids all over the Midwest with our "A" Production Corvettes - Waterford Hills, Grattan, Mid-Ohio, Nelson Ledges, Milwaukee, Blackhawk Farms and, of course, Road America - was an in-period treat that I couldn't get enough of and will never forget. And besides the spectacular noise coming from those machines, the sheer speed was awesome to behold as they devoured every race track they visited. 

And the legendary names that wheeled these machines were a mix of Hall of Famers and hard-scrabble drivers who wouldn't settle for anything less than the fastest, baddest V8s available. The legends were present and accounted for: Ken Miles, Dan Gurney, Roger Penske, Mario Andretti, Jim Hall, Bruce McLaren, Denny Hulme, Jackie Stewart, Peter Revson, John Surtees, Parnelli Jones, George Follmer, Mark Donohue, Swede Savage, Sam Posey, Milt Minter, Ed Leslie, Dr. Dick Thompson ("The Flying Dentist"), Allen Grant, Jerry Grant, et al. And, of course, my brother Tony and his teammate Jerry Thompson. This list of drivers - which I have affectionately dubbed "The Muscle Boys" - were just the tip of the iceberg. There were countless others who wheeled and manhandled their brutal machines at tracks all across the country. They were visceral, no-compromise machines that captivated the hearts and minds of racing enthusiasts, and if you've ever been to a vintage racing event, the same is true today, if not more so. I hope you enjoy the following images and recollections as much as I do.

And that's the High-Octane Truth for this week.

Laguna Seca, October 18, 1964. People forget what a outstanding driver Roger Penske was back in the day. His performance in the 200-mile Monterey Grand Prix, when he swept both heats in his No. 66 Chaparral 2A Chevrolet against the toughest competition the sport had to offer: Dan Gurney, Parnelli Jones, Bruce McLaren, Bob Bondurant, Jerry Grant, Ronnie Bucknum, Ed Leslie, Innes Ireland, Jack Brabham, Charlie Hayes, Augie Pabst, Al Unser, Bobby Unser, et al. was indeed impressive.

Daytona 24 Hours, February 4, 1973. The No. 11 Chevrolet Corvette driven by Tony DeLorenzo runs on the high banks ahead of Francois Cevert (No. 3 Equipe Matra-Simca Matra MS670 V12) and the No. 10 Shierson Racing Chevron B19 driven by Charlie Kemp. The No. 11 was a specially-prepared big-block Corvette that DeLorenzo qualified 6th and because of its tremendous speed on the high banks ran with the leaders in the opening portion of the race. DeLorenzo and co-driver Maurice Carter didn't finish the race. The Cevert/Jean-Pierre Beltoise/Henri Pescarolo Matra qualified 2nd but didn't finish (blown engine). The Shierson Chevron qualified 9th but didn't finish either. The race was won by Peter Gregg/Hurley Haywood (No. 59 Brumos Porsche Garrard Record Players Porsche 911 Carrera RSR).

Sebring, Florida, March 20, 1964. The No. 4 Chevrolet Corvette Grand Sport driven by Jim Hall and Roger Penske during practice for the 12 Hours of Sebring, which would run the next day. The duo started in 7th but finished a disappointing 18th. The Corvette Grand Sports were out in full force for this race to go up against Ken Miles and John Morton in the No. 1 Shelby American 427 Cobra Prototype. A.J. Foyt/John Cannon (No. 2 John Mecom Racing Chevrolet Corvette Grand Sport) battled with Miles the hardest but finished 23rd. The No. 3 Chevrolet Corvette Grand Sport driven by Delmo Johnson/Dave Morgan finished well-down in 32nd position. The Miles/Morton Cobra did not finish due to a blown engine.
