The Goal:

A performance radiator using modern materials that will dimensionally be an exact duplicate of the original stock radiators size and mounting location.  Customer requested that we remake all the mounting brackets and flanges as well out of 1/16" and 1/8" brass plate.

The Vehicle:

A 1928 Stutz Black Hawk Speedster, an original flathead 8 cylinder balanced and blueprinted with 10.5/1 compression and a 4 deuce carburetion system. This vehicle is being built up for racing, and will need all the cooling we can provide.
