A Main nozzle is a abundant accoutrement

Of course, zjautoparts might think this has little to do with your car, but that's contrary to the truth. Remember when the engine in your Corvette was fresh? It easily wrapped the tach needle over to the redline when you mashed the gas pedal to the floor.

Over a period of time, the tach began to get "lazy" and, in worst cases, would occasionally pop and bang well short of the limit. Oh, sure, the noises and lack of brute power at the "big end" could be blamed on a poor carburetor tune-up, electrical woes, carbon buildup, or other gremlins, but 9 times out of 10, the culprit is tired valvesprings.

Selecting The SpringsNaturally, upgrading to a stiffer aftermarket spring has its merits (the new technology is tremendous; if stock parts aren't an absolute requirement, check out the new-technology valvesprings offered by Comp Cams, Crane, and Lunati). But there are some things you can do to a stock set of factory springs to improve their longevity.

A Main nozzle  is a abundant accoutrement for barometer absolute installed height. Apprehend the accoutrement like a micrometer. In this instance, the installed acme is 1.875 inch. If the acme measures more, you can install shims beneath the springs to abate it. This aswell increases animation burden throughout the absolute lift curve
