You dont know of any reasonably priced Dyno rates in the portland area do ya EB? I would be darn curios what kinda numbers I can obtain with my truck. Im sure my gearing is whats killing my seat of the pants tests... 4.10's and 32" tires are just not very friendly. I have a guy that bores throttle bodys for 100$ Im going to be shipping my extra TB out soon. I read a review on a sight where an individual felt the TB boring was a larger improvment than headers+exhaust. Having already done the headers+exh he may have simply amplified his results by addressing the next weakest link in the line who knows?

Is there any industry golden rule that pertains to intake valve size compared to exh valve? Maybe some sort of ratio that works best? What do you think of my hair brained chopped up intake manifold idea? I know from my days working with VW rabbits that the CIS intake manifold was clearly the limiting factor and that any increase in cam lift over a modest amount was simply wasted due to intake manifold runner size.
