Buy the correct cam for a TR and it won't turn any more RPM than it will with a single 4. And the TR will make more bottom and mid power. [/quote]

Was about to post something similar but more exact. Cam does not really dictate max rpm power potential at all. That is all in the induction. Everytime I've used a TR it has lowered RPM peak HP and torque comes up across the board. J.Rob
