I don't think he has a cam yet
And I apologize for not realizing that a 5.9 is always a magnum and a 360 is always a LA
agree with TF60
here is the mechanical advantage
an inverse radius profile can have about 8 degrees less seat timing for the same upper end area under the curve
so a 260 can equal a 268
or you can go 265 and have more area and still get the intake closed earlier for the bottom end
or if your compression is high you can go the same 268 and have a much bigger air breather
question is how did you determine the 9.2- heads most likely cced as you have the flows was there another thread on this build?
you almost have to have custom pistons to get 9.2 in a 5.9 or deck the block or???
I'm getting ready to do mine so very interested in your build
