Deleting the cats, you gotta be careful you dont get piston slap. That back pressure provided by the cats helps the motor in some ways!
WHEN IN DOUBT, YOU CAN NEVER USE TOO MUCH PB BLASTER!

Contact Pat G at EPS. Let him know what you have done and what your plans are in the future and he will spec out a custom cam for you. Guy does amazing work, know quite a few trucks running this stuff.
