I wouldnt bother, I know you do have it, and if you like testing stuff whether its good or bad , then go ahead. I think its going to slow you down.
You have your combo running pretty good as it is. I like to test things that I think will make it faster.
With your Dynamic 4000 or so vert ????, that 272 duration will hurt your 60 ft. and it probably wont recover at the stripe, even though it could MPH a little better.
If your into testing ,
have at it.
You did leave out some important variables, like compression, tire diameter, cars weight, actual vert stall,and header primary tube diameter.
Those are all important Combo factors as well, along with the other known info you posted. So I or anybodys info is just a assumption at this point. Even with all the combos info, they will be , just Better assumptions.
