I have a question for all you hemi experts. What is the difference between a big combustion chamber motor, ie Veney, AJ/WAR and small chamber Brad 5 combo? I realize a big chamber combo takes a heavier piston to get the compression where it needs to be, but is there a difference in power, is one more forgiving than another as far as tune up, easier on parts, etc? In this scenario lets assume that overdrive is not limited, and running a screw blower so boost is not a problem either, so it would not be necessary to spin the motor past 8500-9000 rpm. Any thoughts?
