Thanks for the update.
However: are the 3 openings between the intake ports water connections?
Was the cam supplied by Falconer, or is it a Chevrolet design?
His V12 is based on 2 inline 6's I believe. Chevy designed cam I think. I'm just getting into this. Yes the 3 ports are water outlets they will be plumbed into a remote thermostat housing. The bore spacing is the same as the 292. You would have to talk to Ryan about the design.
