Here is what to expect, but keep in mind that if you make a major change like cams, any stage, the car will need a tune to get the best results. There are many factors that affect the cam's end HP number: headers, porting, exhaust, the tune, cam timing... with that said;
Stage 1 should see 25+ hp
Stage 2 should see 45+ hp
Stage 3 should see 60+ hp
This will also move the torque/hp up in the RPMs a little compared to stock, however, there is little impact on driveability with stage 1s and stage 2s. stage 3s will need more tuning to get a smooth idle/driveability.
If I read the list of mods to your ZR1 correctly, I do not see you have ported your intake/housings. Corey seems to be one of the best tuners out there. Porting is almost vital for the LT5, they like it.. a lot. Without porting, I would guess 20hp, with porting I would imagine a full 30hp. But keep in mind this is not just 30 at one spot, you will notice a much stronger pull almost everywhere.
I personally like the secondary delete, quicker throttle response, IMO.

Yes, Pete ported my heads and intake and I've got SW headers so it sounds like I should see 30+. Something to think about. It's kind of strange knowing my F150 Limited has more power than my ZR-1. Not reason enough to do it but a little more power is always a good thing.
