Stock for stock it's clearly a driver's race, and no amount of name calling in the world eill change that. Trap speeds seem to indicate that the LS1 f-bodies have the power edge, but the Mach has that substantial gearing advantage out of the hole (3.35 first gear, 3.55 final drive for the Mach vs. the 2.66 first gear & 3.42 final drive for the f-body). I say the f-body typically has a bit more potential but you won't find many f-body drivers skilled enough to utilize it. I'm still struggling to ****** a 2.0x short time but these Machs seem to do it with ease. I welcome any Atlanta-area Machs who'd like to make a Friday night run down to SDR for a few runs (good sports only, please). Competition this tight is where the real fun is.
