The 572 c.i.d. MERLIN is one of the most popular engines in the entire World Products lineup. And it’s easy to see why. Most performance enthusiasts who seek serious horsepower appreciate the benefits of a 572 engine. And when they compare what they get in a MERLIN as opposed to the factory crate motor of the same displacement, World wins hands down! Consider that World Products and GM are similar as they are manufacturers that produce their own blocks, cylinder heads, and intake manifolds. But there the big difference lies is that World sources its internal components from the aftermarket and the OEMs use many stock parts. The bottom line is that World engines contain premium grade components from the likes of ARP, Clevite, Eagle, Fel-Pro, Mahle, Manley, Moroso and MSD. Each MERLIN is assembled by experienced, professional engine builders, carefully broken in, and dyno tested.
