Quick Overview

This Merlin III is a specialy prepared Block to Teague Custom Marine Specifications from World Products used to build the 565 Cu. In. Teague engines. This is the block we use to build 1200 horsepower and up.

Prior to the availability of aftermarket blocks, performance enthusiasts were faced with the dilemma of scouring junkyards looking for 4-bolt main blocks or trying to fit 2-bolt blocks with aftermarket cap kits. Now you have a choice between standard 4-bolt main blocks with nodular iron caps and splayed billet caps. Rest assured that the 4-bolt setup will provide excellent reliability for most applications. For the serious performance enthusiast, the splayed billet setup is preferred for several key reasons. The illustration below shows a cross-section of a block casting, and the relationship between bolt holes and the "meat" of the block. As you can see, the splayed bolts have a much better anchor" due to available material thickness. The multi-directional clamping of the splayed bolts also helps improve bottom-end durability.
