[Kamaro Killer]

I was shifting around 5000 rpm's each time I shifted. I tried to vary it, and shift around 4500 rpm's on first gear, and it didn't do anything. I think one of the things that held me back is how long I would spin before I got traction. I have BFG Comp T/A's on the rear in 225/50/16 on a 4 lug rim. I need to get slicks, but I'm not sure which kind to look into, what size (s) to look for, or even how much backspacing I have to use. I am working on getting a tach with a shift light, but money's tight right now (like it ever isn't, lol) so I'm trying to trade someone for their tach. My car's basically a stock engine (see profile for mods, on the 93) seeing as how the s/c is unhooked right now. Any help is appreciated, thanks, Keith
