I’ll say it: The American pushrod V8, and specifically the small-block Chevy (including its later incarnations, the Chevy LS- and LT-series) is the best all-around engine ever made. Period. The performance potential, the popular tuning expertise, the power-to-weight ratio of the latest iteration… Put it all together and you have the best engine ever. This position can be backed up by any number of car enthusiasts; venture to contest it and I’ll wager at least a half-dozen SBC buffs will produce numbers and stats reasserting its superiority.
This declaration may come as a mild surprise to some of you acquainted with my enthusiasm for imports and weird engine tech in general. But a clarification is in order: There’s more than one way to appreciate a powerplant, and the distinction to be made here rests on the difference between two of those ways: Respect and interest.
That said, do I respect the small-block Chevy V8 and its virtues? Absolutely. But does the engine actually interest me? Not in the least.
Put two vehicles side-by-side, say a Corvette Z06 with the factory performance catalog added and a Miata with a homebrew turbo system scavenged from various cars and run with a owner-programmed standalone EMS, and I’ll invariably be drawn to the latter. The Corvette may annihilate the Miata in every way, but how many times have the standard parts (cam, headers, etc) been added to an SBC in the pursuit of power? Yes, it may make a noise that amounts to catnip for most car buffs and spin the tires through third gear, and I have nothing but respect for that. It’s power and that’s always a draw. But let’s do something different. That’s where the interest lies.
I extend that lack of interest in the American pushrod V8 to swap projects involving the engine as well. There seems to be this especially virulent idea in many corners of the automotive world that dropping a pushrod V8 into any car will invariably make it better. Credit the late Carroll Shelby, perhaps, for the genesis of the notion; after all, he was the first to popularize it with his fusion of American muscle and British bodywork into the original Shelby Cobra. And to reiterate my earlier point: In most cases, I can’t argue the numbers—the V8 swap very often makes the resultant car more powerful, more reliable, cheaper to maintain and frequently even lighter and more economical. But is there anything more mind-numbingly boring than, say, a Jaguar XJ6 with an American pushrod V8 swap? Yes, it’s orders of magnitude more reliable, but the car’s distinctive character is gone, its engine note is completely out of sync with the car’s ethos and the whole idea is just so obvious that it loses all appeal.
Respect touches on those qualities I admire in a car: Power, handling and the like. Interest, on the other hand, has to do with qualities I’m drawn to in a scope wider than just the automotive realm: Innovation, creativity, new solutions to old problems that may at first be inferior to their elders but could potentially, with enough development, eclipse the traditional “best way” to do something.
I have a hunch more enthusiasts than just me view their automotive passion this way. If nothing else, maybe it will explain why a lot of car buffs persist in focusing on engine types and swap projects that seem inferior in so many ways to the tried-and-true-and-effective. It’s a matter of interest.
