So in your opinion my low geared rear end is the biggest factor, not the low rev. 235. I didnt mention earlier but you prob. know I have a 2 speed rear end and 4 speed transmission, if those are my limitting factor maybe I should upgrade to the 250 I have for free and get a better head, and live with it. Ive only drive the truck a couple of times (unloaded) and unbled brakes (just topped off emtie res and short off road test drive) the brakes worked quite well ie. I hit the steering wheel they worked so well. Was very surpised since I have read many neg. things about them.
