Mopar's 5.7L and 6.1L Hemi engines are certainly potent, but they haven't garnered the attention of hot rodders to anywhere near the level of GM's LS-series engines. That's too bad, since the new Hemi has a great deal going for it even in stock trim. Like the current LS3, the SRT8 Hemi is blessed with tremendous cylinder heads. Impressive even in stock form, the 6.1L SRT8 heads respond to precision porting every bit as well as the General's heads. A properly ported set of 6.1L Hemi heads (like the ones employed in this buildup from Dr. J's) can flow more than 350 cfm at just 0.600 lift. That is some serious head flow. The SRT8 version of the modern Hemi also sports an impressive factory aluminum long-runner intake, a sizable throttle body, and free-flowing factory exhaust manifolds. There are Hemi owners who think the 425hp factory rating is not only insignificant but downright pedestrian and think nothing about more than doubling the factory power output.

To demonstrate what it takes to produce an honest 1,000 hp with a new Hemi, we decided to take up the folks at Kenne Bell (K-B) and Mr. Norm's on their offer to test one of their massive, new, 3.6L, twin-screw superchargers on a 6.1L Hemi (destined for use in a new Mr. Norm's Super Challenger).
