Looking at the data, the 360 produces its peak torque faster than the 318.
It seems to benefit from a cam. I didnt like the drop in torque for the 318
with a HP cam.
I am going back to the Dyno to find my favorite combo for the 318. I think I
want 360 heads! :0).
What sucks about this program is that it is all theoretical. Motion Software
(who makes this) has a dragstrip program where you can take these engines
from the Dyno 2000 and put them in a vehicle. They claim that you can use
virtually any vehicle/trans...etc. I'm gonna ask them if they have a Dak
simulation as a choice. If so, you know I'm gonna get it.
