LS1 CAM SWAP AND DYNO TEST

When it comes to adding power to your small-block Chevy, the camshaft is an integral part of the performance equation. Luckily for owners of Chevy’s latest iteration (Gen III) of the famous small block, the modern fuel-injected LS1 responds just as well to camshaft upgrades as the LT1s, L79s and L48s of old. Naturally, cam technology has come a long way since the days of the Duntov 30-30 profile. The improvements in cam technology are important, as the new LS1 is head and shoulders above any of the old ’60s and ’70s muscle-car small blocks, regardless of the advertised power ratings.

CRATE OPPORTUNITIES

While it’s not new information that GM Performance Parts provides an assortment of engines to choose from, it’s never been easier to select the one that is best for your budget and the intended purpose of your car.

EARLY-IMPALA LS2 SWAP

Low in its architecture and functionally beautiful, the LS2 engine is an ideal replacement for a previous generation of Chevy powerplants. It offers good
performance, greatly improved economy and plenty of support from an industry leaders.

LS is MORE

When GM introduced the Gen III small block in the F-body, it rekindled a dying performance flame with its new-generation small block. While the Gen I small block actually kick-started the hobby and got it into gear, it’s the latest family of small-block engines that has grabbed the attention of enthusiasts everywhere—and for good reason.

Choosing The Right Cam

Cam-speak is a language all its own. Well, maybe not from a linguistic point of view, but it is a specialized dialect of car-guy talk. Although spoken by a good portion of enthusiasts, Cam-speak is really fully understood by only a handful of those same enthusiasts, as it is a very specialized, nuanced dialect. Those who do not speak the lingo can instantly be singled out. Those who are fluent in cam-speak are listened to intently, even when those listening do not fully comprehend whatʼs being said and how to apply it to their particular applications. Few within our ranks are particularly fluent in this highly specialized jargon.

OUT WITH THE OLD, IN WITH THE NEW

Honda did the right thing in refreshing the looks of the aging DC2 Integra platform, but somewhere along the retooling process, the terrific driving experience for which the Integra was known was lost somewhere. The Integra Type-R was a no-frills, high-performance sport compact that bordered on being a street-legal racecar, but without the loud exhaust or kidney-bruising ride; the RSX Type-S just doesn’t have the feel that the older Integra had—instead of being razor sharp and agile, the RSX feels numbed and subdued by comparison.
