Even though they’re only 540 cubic inches these MERLINs are a step above factory 572 crate engines. Factors like the MERLIN III cast iron block, MERLIN III aluminum heads, and a full compliment of premium grade internal components from leading aftermarket manufacturers make the difference. Add to the fact that each engine is dyno tested and backed by a 2 year/24K mile limited warranty (street applications only) and you can see why the advantage goes to World Products.
