McLain's Automotive Specialty Tools and PartsPDF files are viewed by using Adobe Acrobat Reader which is avaliable free over the internet. The first of the files is a photo essay on a 557 cubic inch Big Block Ford engine. This engine was built using the EX-514 heads from Flow Technologies and the whole purpose of the build was to demonstrate what their heads could do on a simple and low dollar short block. The next PDF is the manual for the Predator Carburetor. I've been told that their website has been down and this document is not easy to find. Predator carburetors while rather unusual in design are very functional pieces which run very good on many different engines but are particularly effective on a tunnel ram or supercharger.
