Default complete topend rebuild!!

Alright guys, I have been getting some on again off again lifter tick on the highway and my water pump is shot. So I have a little project this weekend. heres a list of everything:

PRC 5.3 stage 2.5 heads
ls7 lifters
LC1 wideband
new water pump & thermostat
trans temp gauge
re tune

I have some recent 1/8 mile times with this little trailblazer converter and it dynoed 376HP. I'll be going back to the track/dyno after its done. I think my compression will be close to 11.1 so i'll probably move from 89 to 93 octane as well to get the most out of the tune.

Any comments, suggestions are welcome, also if your around N. Ft. Worth sunday feel free to come by and give me a hand.

And for anyone wondering, I lowered my truck back down last week. Being lifted lasted a whole 2 months

Your truck look so much better with that stance. The 2.5 5.3s should put you over 400 rwhp
