Wraith 6.2L 380+ bhp

V8 Small Block Chevy 377cid

This is an extremely versatile engine, designed for the discerning owner as an upgrade or replacement for virtually any of the small block series engines. When used to replace the 300 / 350 range it provides a quite considerable improvement in performance that will make you wish you had upgraded sooner. With virtually no fuel penalty at all cruising speeds it really is hard to resist. It will deliver a very noticeable improvement in performance and throttle response that will make you smile.

A glance at the improvement in BHP and specification will show that this engine gives exceptional value for money. Like all Swaymar special series engines this too delivers a lot more torque and BHP several hundred rpm lower down the rev range than its factory replacement counterpart. Specifically designed for Hi-torque, this engine is perfect for marine applications. These carefully considered engineering improvements result in a considerably faster boat but without the usual fuel penalties associated with more power.
