Picking up or dropping off your engine? Do what Bruce Mann just did and rent a van from Home Depot. $150 a day with unlimited miles! It can be raining and everything stays dry. Don't want to chance a scratch on your new truck. Your old truck is good for around town but Brownsburg Indiana is farther than you trust it for. Whatever the reason, this beats us shipping it for $500 and it gives you a chance to take a nice drive and check out the shop.

The High Performance Injuns Story

Our Love for Pontiacs started with my first car at age 13, a 1964 Tempest 6 cyl 3 on the tree and by the time I had my license I had traded several cars around - the Tempest for an overheating ‘67 GTO Automatic, then the ‘67 GTO for a 4 Speed ‘66 GTO. I had that car all through High School and raced it regularly at OCIR in California.

After Marine Corp Boot Camp I bought a ‘64 GTO that I still have 38 years later. I also have a 6.00 Tagged 220” Rear Engine Pontiac Powered Dragster and “GoatZilla”, a 6.00 Tagged 2400# ‘64 GTO. These cars are all rolling Dynos used to test, prove and improve everything we are planning to bring to the market.

High Performance Injuns started out selling “Injun Kits” with a small ad in High Performance Pontiac Magazine and quickly grew into a full service “Injun Building Enterprise”.

We have grown to now include the creation of Pontiac Cast and Billet Cylinder Heads with many more upcoming products for Pontiac’s created through years of experience and plenty of “Injunuity!”
