Notice the Vol eff goes up (as does the HP ), this leads most to believe that these heads are flowing better with this smaller displacement (I believe these heads were designed for a 327) than they are with the 383, with out a doubt the 383 would benefit greatly from better flowing heads.(which can be compared with this software along with all other paramators)
The 383 of course wins the torque war in this sim and seat of the pants real world feeling.
When I post these sim generated graphs it is to pass alone the best info I can come up, use it how you will, or mock it as you may.
