RE: [Chevelle-List] 4.10 gears

[Walchuck, Rich]

I have a 4.10 in my el Camino and run about 3500 to 3700 at 70 MPH.  I only have them because that is what came in the car from the factory.  I would like to change to even a 3.73 on 3.50, but I believe with a 12 bolt 4 series carrier you can only go to 3.73\ unless you change the carrier.   Rich -----Original Message----- From: Neckster [mailto:[EMAIL PROTECTED]] Sent: Wednesday, July 25, 2001 2:48 AM To: [EMAIL PROTECTED] Subject: [Chevelle-List] 4.10 gears I currently have 3.08 gears in my 10 bolt, and I keep seeing alot of people running 4.10's.  What kind of rpm's does that give you at freeway speeds??  Is your car "comfortable" doing 70 mph on the freeway with these?  I was thinking of 3.50's, but if the rpm's aren't too bad, maybe I'll go 4.10's. BTW- I have a 2400 stall, and I'm running 295/50/15 tires.   Thanx, Trevor
