Video: Watch This Boosted 540ci ’71 ‘Cuda Spin The Dyno With 1,600-Plus-HP

OK, we gotta admit; we’ve got a sweet spot for Mopars winding up the dyno rollers with well over 1,000 horsepower. Now, to make that kind of power, you best be looking at the business end of a supercharged, bottle-fed nitrous monster, an alcohol-burning dragster or a street machine touting one or two (or more turbos), and the ’71 Plymouth ‘Cuda in question here is brandishing the latter.

Propelled by a Steve Morris Engines-built Indy Maxx aluminum block topped with Indy 572 aluminum cylinder heads with all Steve Morris internals (cam, pistons, rods, crank, etc.), and controlled with a FAST XFI fuel injection system, the big bore-and-stroke Indy big block was built over two years prior to this video’s filming (published April 2013) for owner Joe Katz (sp).

The gunmetal gray ‘Cuda is obviously designed for over-the-top street machine use, as well as a healthy presence on the dragstrip, and with the powerplant its got between its tube chassis framerails, it should do great at both. When the pleasantries are concluded, the ‘Cuda – christened “Rumble Fish” – is spun up at Steve Morris Engines’ chassis dyno where, in a matter of mere seconds records a staggering 1607 rear wheel horsepower. That’s right, we’re not talking at the flywheel, but over 1,600 horsepower where the rubber meets the asphalt. That is a lot of power.
