Big Block 250 2V street supercharger, complete 8mm kit.

A 71 style Supercharger sticking out of the hood is always a nice addition, but it may not be what you are looking for. With our 250 billet blower series we have solved that problem. Still producing the most boost in the industry, these dangerously powerful superchargers come in a beautifully small package.  Perfect for tight clearances and low profile under-the-hood applications.

Complete Kit for Big Block Chevy.
