Ok, so I just picked up another 2wd RCSS 5.3 '99 Silverado after kicking myself for the past year when I sold my other '99 . I still have the '02 LS6 cam/valve springs, and 7.450 hardened Trick Flow pushrods that never made it into my old truck and now they are going into this one. I've spent a lot of time reading old posts and other internet sights, but still don't really have a definitive answer. This is my setup:

5.3/auto
Pacesetter LT's and y-pipe into 3" Hooker muffler
K&N CAI
'02 LS6 cam/springs
Trick Flow 7.450 pushrods
Stock 5.3 heads
Tuned (not sure by who, yet)
3.42 posi

My question is, are the 7.450 push rods correct for my application? I have read about the .050 smaller base circle, which is actually .025" smaller per side. Will I cause any damage (valve-to-piston clearance, spring binding, etc) using a pushrod that is essentially .025 longer than original? Should I spend the $$ to get the 7.425" pr's? I'm doing this truck on a student's budget, so I can't get the best of the best (hence why I am using a $150 cam/spring combo). Also, what kind of 1/4 times should I expect when it is finished? I am hoping for a realistic low 14.

Any input from guys that have the LS6 cam in their truck is greatly appreciated.
