Ok guyz I have got a quick relatively stupid question,what rpm should I be shifting at? My car is a 96' z28,K&N cai,tb bypass,flowmaster exhaust,and stock gears (3.23 I assume) with no cam or head alterations. I have been shifting it at 5k but after reading a few threads and comments I am beginning to wonder if I am cutting myself short. Any input is greatly appreciated!!!
