We get these emails and calls from time to time:

"Hi,
I had a engine built by High Performance Injuns from Rialto California, in 1990-91. It still runs great. Just wondering if you are the same company or builder?
Thanks
Greg"

Anyone else out there from back in the day?

We do so many aluminum heads that it’s great to see a set of good old cast iron Musclecar heads for this ‘68 GTO build. Hardened seats and dished pistons keep it pump gas friendly!

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!”
