Just wanted to update those who were posting about my performance issues back in march.
You may recall that I seemed to have no power with my 396, so checked the cranking compression and it was 150 psi, installed a set of closed chamber heads (had open chamber on previously)and had a noticeable gain but still left me wanting some more (figured gears would do the trick). I then junked my old restrictive 2 1/4" exhaust system with stock mufflers & 2 " tails, , and installed a 2 1/2" X-pipe system from Pypes and a pair of Summit turbos. Wow, like who turned on the lights!! smile.gif I cannot get traction at all in first gear anymore, it just smokes the right tire and shoots right for redline !! I was absolutely amazed that the exhaust upgrade made that much difference. Now its time to save those pennies and upgrade to posi. I am one happy camper now.
