3.42s work the best with my camshaft I have found - in na form. But the 3.73s are the most comfortable for me when I use a 200-4r at hiway cruise.
I had a breakthrough moment last night when a thought on boost referencing the power system popped into my head from nowhere. Amazing how you can just let things sit in your mind awhile and they get sorted out sometimes. This 7043244 core doesnt have the best setup for access to the base of the power piston but it is doable.
