Info

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.

FREE freight on select World Products crate engines!

Crate engines are shipped freight paid with a common carrier within the 48 states (not in Alaska or Hawaii). They have to be shipped to a business address to receive free freight. It can be shipped to a residential address for a $60 fee. Please be sure to provide a business name and address in the shipping field if going to a business. 

This item is garage sale priced because it has been discontinued from our current product line.

NO WARRANTY, NO RETURNS ON GARAGE SALE ITEMS
