Congrats Lynn! It would be neat to see a Pontiac in C/SM against other wedge motors!

These new cylinder heads are an amazing piece of engineering. They remind a little of a set of heads from Mickey Thompson that the late "Jungle" Jim Liberman and Lew Arrington had for their first funny car, a 1965 GTO."BRUTUS" They only lasted one run though due to a 25% load of nitro and the supercharger. They then got some M/T hemi heads but quickly switched to the tried and true 392 Chrysler engine that would handle the nitro and blowers of the day. It sure will be interesting to watch the cars perform with them. Great job to the guys who persisted developing this new product.
