4.10 rear end gears!! Arghhh
Even with the 700R4 locked up, with 295/50/16 BFG's on it, Im turning 2500rpm cruisin on the fwy here, and I pretty much have to stay in the right lane (70mph is WAY slow on the fwy here! So cal!)
Im thinking about switching back to 3.42's.... The problem is... the rear end is new, new Posi, and the rear end built with all new bearings, 5 lug axles, etc.. Thinking about maybe looking for someone to trade out with a tight Posi'd 3.42 or... I dunno Just a bit too short, hell, with the motor in it now, I could run 3.08's with no issue, but cruise would drop way down... 72mph = 2500 rpm - 4.10 72mph = 2100 rpm - 3.42 72mph = 1900 rpm - 3.08 The drawback is that I have a Victor intake with a spacer, and where it has plenty of git, it will be runnign a bit below the torque curve with the lower gear, and with it the loss in mileage... Ideas?? Wanna trade? lol Will
