H/C/I...breaking in and tuning questions
I'm doing serious modifications to my baby this winter and I had some questions before I get too far into it. My mods are these:
Ported 5.3L Heads (milled to 60cc)
Torquer V.2 Cam
LS6 Intake
38# Injectors
LS7 Lifters
PRC Double Valve Springs
and all other supporting mods
I was wondering...
When I'm done putting everything together what should be my course of action? I was planning on not even starting the car, towing it down to Richmond, and having Steve tune it right away. BUT...the cam install booklet that came with my cam says I should "break in" the cam for 30 minutes at 2000-2500rpms. The problem is that I'm bumping the compression up a little and increasing the injector size to a point that I'm afraid I'll run into predetonation without a tune.

Only break-in you should worry about is heat cycling the springs first, while not going over 2500rpm like your booklet mentioned. Tuner should be able to get some baseline readings and data logging and tune for the injectors to prevent any detonation for the time being. Once the springs fully cool, he'll be able to finish off any needed tuning, including the WOT kind!

You'll be fine to start it. I went from a bolton small cam tune to 60# injectors, biger fuel pump, 317 heads, differant cam, lost a point in compression, and a blower. I put about 50-100 miles on my car. You have to burp all the air out of the coolant, and I would give the engine 2-3 heat cycles then change the oil and filter. Make sure it pumping oil and every thing sounds ok ect...ect. Then tow it to the tuner. Bring a extra set of spark plugs to the tuner my need them.

I'm going to do an almost identical install ( probably be closer to march before i can do it though) so even if they sound stupid remember they are sincere.
why an extra set of spark plugs.
what benefit are the LS7 lifters?
What kind of compression ratio will you get with the heads milled to 60CC?
how did you decide on injector size?
