It really doesn't, but I could alter the gear ratio some. I wanted to retain 3.55 gears with a 727 trans and maybe 2500 stall. I could always go 3.91s and/or a 3000 stall if needed. One of my problems is that I'm unfamiliar with the characteristics of a Gen 3 when you get up there in duration. My 5.7L 300s is crazy quick off the line, all stock, with a 2.62 rear gear and 20" wheels, etc. I know a stock one with short timing is a torque monster, and all the dyno tests I've seen on EFI engines (long manifold runners) with 260/268/273 etc. Comp cams show torque taking a pretty big hit with an increase in duration. I think I better err small, to avoid a 318 or 383-like loss in torque with the bigger cam listed. I know it will rev as high as I'll need with the small cam, just might limit peak numbers.
