MERLIN HARDCORE
BIG BLOCK CHEVROLET
COMPLETE STREET ENGINES

You’ll probably want to compare these big-inch “Hardcore” engines to the OEM 572/620, and conclude that you can get far more bang for your buck right here. Our 572, which is based on a race-proven Merlin block and cylinder heads, is loaded with forged and balanced rotating assemblies and premium performance parts. It's dyno-certified to produce over one hundred horsepower more than the factory crate motor, costs substantially less, and comes with a 2-year warranty. Is there any question? Our 540 puts out nearly as much power as the corporate 572 and costs about three thousand bucks less. You do the math!
