Our Ram Air VI engine is our modern take on the legendary Ram air series of engines These new 6.6 are the same displacements as the older ram airs, so why not bring them back!
The L8T iron block is a solid foundation on its own. It performs well, and if you don’t mind the extra weight, it gets the job done… even if it comes with a few quirks. Nobody’s perfect.
Where we took things further was by stuffing the L8T 8-counterweight crank into an aluminum L86 / L87 / LT1 block, paired with a lightened forged rod and custom piston with a touch more compression. As usual, we upgraded the camshaft, deleted VVT, and installed stronger valve springs and pushrods to support the larger cam.
What you're left with is a 650+ horsepower engine that behaves when you want it to and absolutely rips when you need it to. A modern big-block feel without the big-block weight.
