I need your input.
I need your input. I am pretty new to ls1's and I just picked up a pretty sweet little ride. I traded my turbo Mustang (fox body coupe) for a 1999 Z28. I have been searching the site and I have found a lot of helpful information! I have a few of my own questions that I would like to hear your opinions on.
I have a stock short block with the T-rex v1 cam. Texas speed 5.3 litter stage 3 heads. Texas speed does not have the stage 3 heads listed. I was told the difference from 2.5 to stage 3 is the design of the cnc porting job.
I have a set of comp R lifters. Are they worth using or what would you recommend?
I plan on using Arp head bolts. What head gaskets do you recomend?
What injectors would work best with E85?
Will I run into any problems with stock rockers?
I have a built 4l60e with TCI 4400 stall. Will the rearend last very long at all If I have a good hooking car?
Thats all I can think of for now. Sorry for asking newbie questions!!
All your advise will be appreciated!

All your advise will be appreciated!Head gaskets.. well, you may as well go .040 cometic, you're going to have to flycut anyways, might as well cut a little deeper and bring compression up.
The rear could last a bit with stock gearing, but it could go at anytime with drag radials or slicks. If you go up to a 4:10 or so.. which would be wise with the big cam that likes to be spun to 7k.. it will make it a bit weaker and more liely to fail.
Also, is your 99 bottom end stock? I would change the rod bolts if it is, shifting at 7200 with the stock 99 gm rod bolts will lead to disaster eventually.. likely sooner than later.
