K & M Performance Parts is dedicated to manufacturing the highest quality aftermarket Pontiac engine blocks available.  Our extensive research and product development, which ranges from street engines to some of the highest horsepower Pontiac race engines in the country, has given us the knowledge few if any others in the Pontiac racing industry possess. We have made corrections to yield a superior aftermarket Pontiac engine block.    

To help insure that you the customer get the highest quality parts available, we perform all of the machine work in house on our K&M, company owned, CNC milling center. What this means to you is the Pontiac block you get from K&M Performance Parts is of the same quality and strength as the blocks we use in our own Pro Mod race cars.  You may never need a Pontiac block capable of withstanding well over 2000 horsepower but if you do, that quality and strength is there.
