540303   454 CHEVY  2" JET / V-DRIVE HEADER (FRESH WATER)36" OVERALL WIDTH                                                                                                            

Our Jet / V-Drive fresh water header incorporates a 2" primary tube (1 7/8" I.D.)  The 2" primary tube header has been Dyno tested with our 632 cubic inch Chevy test engine with outstanding results.  For more info click here. The standard collector length is 8" and points down at approx. 36 degrees. In many Jet and V-drive applications where there is extra space between the engine and transom, this can be used to add collector length to help combat reversion.   Keep in mind, that if the  exhaust tips are below the water line, the header can literally pull water up from outside the boat.

Camshaft selection is very important to guard against reversion.  Lightning has many camshaft and lifter options from mild to wild.  We also have dry tail pipe extensions that can eliminate reversion completely.

The standard Header comes with a black powder coat finish; optional colors available. The headers come complete with water supply manifold, gaskets, bolts, pet cocks, water feed hose and clamps.
