Tastes vary, of course, but if you can pick one Chevrolet year that has captured the hearts of Chevy enthusiasts more than any other, hands down, it’s the ’69 Camaro. These cars have become the most favored vintage Chevy of our times. Even though they have enjoyed a growing popularity over time, today they are more popular than ever. This vintage Camaro has outpaced even earlier Chevy classics and all the other models that followed. That’s right—the same year Armstrong and Aldrin landed on the moon, and Woodstock rocked the hippie movement, the newly revised Camaro made a lasting impression, one that would ultimately become an obsession for legions of followers who would have to have one in the worst way.

Much like Camaros produced the two prior years, the ’69s offered relatively good handling for their day, but when fitted with today’s well-engineered suspension components, wheels and tires, they can easily hang in with more modern vehicle offerings, and that’s true for several performance parameters. All it takes is the right selection of modernized components, good planning and thorough execution.

When it comes to the drivetrain, first-generation Camaros respond well to performance upgrades, which now number in the thousands as far as performance options are concerned. And there’s no right or wrong way to modernize an older classic Camaro, as long as what you do is done well, and the parts selected are well balanced for your intentions. Yet, as hard as you try, and with all the money, expertise and invention available, achieving a high degree of efficiency requires the right late-model parts. And when you speak of power and efficiency, the LS-series engines rank right at the top of the list. Of course, if you are inclined to have a big block, that’s different, but there are LS engines that will provide the useable power of a big block but without the weight penalty. It’s not quite the same for those who want to say they have a big-block Camaro, but as far as performance is concerned, you certainly can duplicate big-block power. What’s more, for nearly the cost of upgrading and rebuilding an old small block with power similar to an LS engine, and for generally less than the cost of a well-running big block, you can order a new LS crate motor, or you can do what was done here: buy a used one. An LS, especially an all-aluminum version, is an easy fit, and it’s just the thing to take off a few pounds, thereby increasing power and performance.

We recently had the opportunity to hook up with Mark Campbell and his crew from Street & Performance as they did what many enthusiasts are doing today, swapping out the old for the new. This particular Camaro had enjoyed its days heating pavement with big-block Chevy power, and yet, although it was fun while it lasted, shelling out paychecks to feed it was growing old, and fast. Fortunately, the car’s keeper, Gary Johnson, owned a wrecking yard stacked high with LS2 engines, which just happened to be what his friends at S&P recommended. Utilizing Street & Performance’s basic installation package, he was able to replace the engine in a matter of hours, and by the end of the weekend, Johnson’s classic Camaro was an entirely different animal.

No longer does he fear that stepping on the gas pedal will add unusual cost to the operation of his Camaro, as his new engine choice transformed the Camaro dramatically. It now has a milder street manner than the big block, and that drastic change starts on the first turn of the crank. Its throttle response is snappier, despite its relatively diminutive displacement, and it weighs less, which is reflected directly in tenths of seconds. Best of all, the LS2 has made an incredible difference in gas consumption, improving combined mileage by well over 10 mpg, on average. Sure, when the pedal is to the metal, you can still burn through the stuff, but even then it’s a considerable improvement compared to what the big Chevy engine consumed.

Whether you follow the crowd in search of their next ’69 Camaro, or if you prefer either of the preceding years, there’s no better way to improve the performance of these first-generation favorites. Armed with the right tools to properly install the S&P components that S&P has been refining for decades, you’ll be able to transform these aged classics into a more modern-day road car, capable of doing what was once impossible, such as 12-second quarter-mile times and 20-plus mpg, plus an all-new level of reliability. Here’s how it was done.
