To demonstrate the engine’s viability as a crate motor and also its compatibility with four wheels, Mercury Racing slightly modified
its QC4v engine and stuffed it into what originally was an Ultimate kit car. It was a snug fit, but the engine sits nicely in the
2-seater just in front of a Ford GT trans-axle.
The QC4v will be available from a basic long-block to a turn-key offering.
Every engine is basically custom built at Mercury Racing, giving customers plenty of choices in configuration as well as colors.

But we thought all along about an automotive platform because of the torque curve, says Mercury’s Rick Mackie.
“It’s capable of 1,350 horsepower on pump fuel,” adds Mackie, adding that the 1650 marine version makes
1,650 horsepower on 112-octane race fuel.
The alloy block features NiCom-coated cylinder bores measuring 4.57 inches,
And the crank stroke extends 4.21 inches for a total displacement of 552 ci.
The crankcase is a dry-sump design with oil scavenged from three locations.
Oil return from the top end is mostly through huge passages leading down through each timing-chain
Cover as well as smaller ports on each head that drain lubricant back through the block to the sump.
