Is apples to apples even possible in a perfect world?..
We know that not one of us is running the same exact identical combination. Some of us are running the same heads or the same carburetor or the same cam. But generally other things will be different. Let alone the car that it's in the traction that it's getting through its particular set up whether it be SS Springs caltracs ladder bars etc. Let alone transmission kind and internal setup...
Let alone the conditions of the day...
And let's not forget goals.. Street? Strip? Street/strip? Strip only?...
And another thing was your apples to apples tested on a dyno? And absolutely everything else the same? Was it seat of the pants?...
