72 upgrade

Sounds like somebody need to come up with a way to mill out the stock 1 BBL manifold so it will take a common 2 BBL....I'd be surprised that this has not been done. Also, part of the Super Six setup that seems to be going for big bucks these days is the auto trans kickdown linkage.... another small fab project.

Understood on the Q-jet. I just know from personal experience how the 4 BBL will dissappoint when the breathing is not there; you open up the secondaries and 'meh'... not the kick one expects. At least the OP has the later cam which breathes a bit better than the older stock cam.
