Whether you're into classic or late-model Mopars, there's no doubt that the new 5.7, 6.1, and 6.4 Hemi engines can provide the power to satisfy any enthusiast's need for speed. Though small in displacement...Read more...

We have all heard the hype and seen the cool commercials with the beat-up Duster, the new Hemi-powered truck, and even a front engine dragster sporting a first-generation Hemi, but does the new Hemi engine live up to our expectations? Read more...

With so many intake manifolds on the market, it can be difficult to decide just which one is correct for your application.

The '07 Mopar Muscle/Amsoil Engine Challenge featured the Chrysler small-block, and the engine builders certainly impressed us with the power their engines made.

In the initial testing of our Mauler 440 engine project, we had a chance to see how close our selection of parts came to meeting the stout objectives we originally set. The one thing that stood out from that test session was that our combination was overwhelming the capabilities of the flat-tappet hydraulic camshaft we were running. Read more...

For some, the ritual of hauling a grease-encrusted engine in the trunk of their car to the machine shop is something to look forward to. It's a new lease on life for a tired engine, and the promise of more power and better performance. For others, it's a ritual requiring time, patience, and even more time. Read more...
