What RPM? Hey guys, I haven't had a chance to dyno my car yet, but I know some of you have had alot of experience with the LT1. I'm trying to decide what RPM to rev to for a baseline; Bryan from PCM4Less can send me tunercat files via e-mail to reflash so I can change it. I was originally limited at 6100rpm and it would sometimes hit the limited before it shifted, but it felt like it was still pulling like crazy. What RPM do you guys think I would be safe too, is 7000rpm out of the question? Here are my engine specs and supporting mods:

sounds to me that your bottom end will hold the 7000 rpm with no problem, but i don't know the operating range for your cam. if your cam makes power to 7000 then you should have no problem.
