Here is something good for the 3.8 owners -

As the aftermarket's foremost authority on late-model GM performance vehicles, SLP Performance Parts was among the first companies to develop power-enhancing hardware for the 3.8-liter W-Body. Now SLP is taking W-Body bolt-ons to the next level, with the introduction of our exclusive 1.8-ratio roller rockers for 3800-Series V6 engines.

As the workhorse of GM's passenger-car powertrain lineup, the 3800 is equipped with a mild camshaft suitable for use in a variety of vehicle applications. Simply increasing the rocker-arm ratio from 1.6 to 1.8 yields valve-lift figures of .464/.459" (stock is .413/.408")-enough to boost output by as much as 10 hp, with no adverse effect on drivability.

Figures were obtained through rigorous testing of street-driven W-Bodies and have proved replicable on SLP's in-house SuperFlow chassis dyno.

These rocker arms are manufactured from high-strength T6 aluminum and feature a roller trunnion and tip that significantly reduce valvetrain friction over the stock steel units. Best of all, no valve-cover modifications or spacers are required for installation.

Note: Fits any 1997-2003 W-Body equipped with a supercharged or naturally aspirated 3800 V6. Package includes rocker arms, pushrods, detailed installation instructions, and all necessary hardware.

Each rocker bears the SLP Performance Parts logo.

This package is now listed in the V6 induction section of our website.

Have a good day,

W-Body? Is that the Bonneville and that line of cars? Will it fit a V6 F-Body?

 

the 3.8L in the F-body is a 3800
