LS3 Stroker Cam Swap

1

Words and Photos: Richard Holdener The camshaft is one of the key components in the success of any LS build. Even if you have a serious stroker with the best flowing heads and the hottest intake, they can’t be expected to provide optimum performance without the right cam timing.

Blowers, cams, and big blocks, oh my!

Words and Photos: Richard Holdener Unless you have been hiding under a rock for the last decade or two, the hottest thing going right now is the LS engine family.

Ford 306 Cam Swap

LEAD

Words And Photos: Richard Holdener Nostalgia is a funny thing. Case in point, the original muscle cars. Naturally, we fondly remember the hot muscle motors of the original muscle car era, but truth be told, are these memories tainted or otherwise artificially enhanced by nostalgia? As powerful as the original Mustang, Camaro, and Challenger motors were, the new ones are even ... Read More »

Run with the FAST, the normally aspirated 5.3L also produced 486 HP, but at 6,800 RPM. Torque production was up with the FAST intake, to a peak of 425 lb-ft at 5,000 RPM.

Words & Photos By: Richard Holdener Back in Part 1, we compared a couple of popular intake manifolds on a normally aspirated 5.3L. The FAST LSXR and LSXRT have long been the go-to intake of choice for performance LS applications, but with so many new intakes available, we wanted to see if the FAST design was still a player.
