Can anybody (who has 4:11 gears) tell me what rpm I can expect to run at on the highway (say around 60-70 mph) if I do decide to upgrade from my 3:55s?
Second it depends a bit on how tall your tire/rim combo is. On my Ponys with somewhat low profile tire (245/50) i run around 2700rpm at 70mph. Taller tires will help bring your highway RPMs down.
That's what I thought....but everybody here in my brokerage firm was telling me that 4:10s were a GM gear and that Ford's were the 4:11s. Sorry about that.....but anway.
Shoot! 3k rpms is NOT that bad with 4:10s. Everybody else opined that 4:10s (4:11s) would put me at around 4k rpms on the highway. I didn't think it would wind me up THAT high....but, in any event, thanks for clearing that up for me.
