Hey Man! I'm envious of your build and I have thought about this many times. I have also considered doing stage 1 first like you did. I have a few questions and hope I'm not being to nosey but here goes?
1) Was there any discussion about using Johnson lifters rather than the LS7s? That seems to be a topic from time to time when doing cam swaps. (2) Did you do any of the work yourself? I wondered if Vengeance was OK with that or if they wanted to do everything turn key? (3) I have emissions testing in my county. Do you have that and did they ever mention how that would work? (3) Any chance of you posting a sound clip? Congrats!!!
