Have you got the cam fixed yet? I wouldn't run it without getting it taken care of. As for the UDP I would suggest it only if you break your stock pulley or your looking to squeeze a tiny bit more out of it. For example if you we're to be sitting at 13.0 and looking for 12s a UPD might get you there. The difference will be 5-10hp or maybe 1/10 in the 1/4 mile.

nope havent sent it out yet. some place in oregon is gonna do it. Just use the specs and make an exact copy. I figured since I had it off might as well throw a UDP on it. Iv been so busy with so many things its crazy. Closing on a house the end of the month. I think im gonna wait to do anything to the truck towards the end of the year when it gets a lot cooler. Its like 100 degrees here everyday. waste of time really...
