Ed: After being away for a few days and reading all the posts I realize I should have been more clear at the beginning.
When I stated everything had to be rebuilt I should have stated that many other performance modes were done to my rig. Just the custom ground roller cam and 2800 stall converter alone are worth alot of power.
Maybe my rig did not need to be completely rebuilt. But I have a warranty to back the work done by LPE. I do not mean just the 36/36 offered by Magn. on the SC alone, but a drivetrain warranty from LPE good for 24/24. Much of the work can be done at the dealer for LPE.
I will say this, if you go with just the SC you will probably have minimal problems as heve been expressed here. But, remember the transmission is a very weak link and it would be in your best interest to have it upgraded.
I say Go For It. You will be amazed at the difference.
