Pontiac 453 race motor
The motor is a 1965 421 four bolt main. It was assembled by Kauffman and dynoed at 662 hp with a 950 carb. I added a vacuum pump and 1150 Dominator carb, which probably brought the HP to 700. The motor runs great and recorded a best of 10.10 in the 1/4 mile in a 3,450lb car(without the driver). The motor will only need a vacuum pump and carb. I have a DUI distributor that was on the motor that will be included.

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
