Hello everyone

Ive been trying to get everything in line for my 5.3 build and I was wondering if I could get some opinions. I have a 2000 lm7 thats apart and im rebuilding with new rings bearings and gaskets. I have a set of mildly ported ls6 heads im going to have milled 0.030 to match the compression of the other heads I have. with a set of good dual hive springs, I want to use the tr220 cam as I see it having the best gains for a off the shelf cam. paired with an ls6 intake, and a 100-150 shot of nitrous, I plan to see upper 400 lower 500 hp and torque to the wheels. does this sound correct? im open to all opinions

Take the mods your doing and estimate the gains from those on the low side and then read this thread posted a few days ago, should give a rough estimate:

Wouldnt hurt to watch a few stock/mild 5.3 dyno Vids on youtube, collectively they should give you a better estimate.
