Cam'd Up Our cam was ordered...
Our cam was ordered with the patented nitriding process, which uses pulsed nitrogen plasma to infuse nitrogen ions into the steel. In order words, it's the best way to increase the hardness and lubricity of flat tappet cams to help enhance break-in and durability.

With the new cam lubed up and stuffed in, we fitted the timing gear and chain back onto the front of the motor. We made sure to line up the timing marks before we bolted it down and folded over our cam plate.

Heavy Lifting We used hydraulic...
We used hydraulic flat tappets not only because they're simple to install and reliable, but also to keep the cost down compared to their roller counterparts. We ordered our Comp lifters in the Pro Magnum series, which tend to run $15 more than the normal lifters, but they're designed for added load and upper-rpm hits, which makes them a perfect match to our blower combination.
Our Fel-Pro gaskets were next....
Our Fel-Pro gaskets were next. We applied silicone on the water ports, laid down the gaskets, and planted the supplied Holley blower manifold. We reused our old bolts, tightening them to 15 ft-lb.

Weiand supplies a gasket and includes the four bolts for the blower assembly. We added a bit of antiseize to the threads for good measure and torqued the unit down to 10 ft-lb.
