Will 340 heads fit a 318?

The problem with all the 340/360 heads on a 318 is the chamber measures about 70 cc, which will drop the compression to an unworkable low ratio on a 318. You can forget about decent performance with these heads and the stock pistons, so again, a set of moderately priced aftermarket pistons is the answer.

How does centrifugal supercharger work?

A centrifugal supercharger is driven by the engine itself. A pulley attached to the engine spins a belt that in turn spins the supercharger. The impeller on the supercharger then sucks in air through an air filter. A bit of piping then feeds that air either into an intercooler or straight into the engine.
