1931 Hal Donovan Custom Roadster

The Build

This coupe is one of a kind. We started by custom fabricating a chassis from scratch then we took a rare 4 cylinder Donovan aluminum block and added a Hal Overhead Cam conversion. Then we added a supercharger with a custom side draft intake manifold and dual SCC Winfield Carburetors with side draft conversions.  We put in a 4L60e transmission with CompuShift and a custom stainless steel exhaust system. It became a rolling chassis with Wheelsmith Wire wheels. This was built to showcase our work for the 2015 Grand National Roadster Show and is currently for sale!
