With the recent changes at John Force Racing is it fair to say that JFR is now a non-Prock-fit organization?

SOLD but we can always get you a new one!
Looking to build a Mega Boosted, Max Effort Nitrous or Full Blown Nitro I***n? This SOLID Aluminum block may be just the ticket.

No Coolant through the block so not something you want to hot lap at the bracket races but ideal for setting that quickest Pontiac record.

All Pontiac "Big Chief" solid aluminum block. 4.350" bore. Has been running on the Dyno, switched to water jacketed block. 55mm cam bore. .903 lifter bore.

These blocks receive the HIP process as a standard procedure and sell new for $6595 less the sleeves. Sleeves are $800 additional so you're looking at $7395 to buy this new plus some extra money for machine work.

For Sale outright or as part of a build through us at $5000.

The High Performance I***ns 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 I***ns started out selling “I***n Kits” with a small ad in High Performance Pontiac Magazine and quickly grew into a full service “I***n 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 “I***nuity!”
