Hi, For 12 bolt C axle I know that Richmond makes two different sets of 3,73's one for the 3 series carrier and one for the 4 series carrier. They also make 4,88 4,56 4,10 3,90 to fit the 3 series carrier I don't think that you can go lower than 3,73 with the 4 series carrier. I installed this gears last summer behind a small block and a Muncie, it's a little bit short on the top end but it should be ok behind your possible 0,70 ratio on 4th gear which would make it a 2,61 André -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] On Behalf Of richard a schaefer Sent: 23. januar 2002 20:29 To: [EMAIL PROTECTED] Subject: Re: [Chevelle-List] Rear End Ratios Replies to this message are sent to The Chevelle Mailing List ------------------------------------------------------------ I agre with clint. Behind the torque of a big block 3.31 or 3.55 will work nicely, especially with an OD. I have a s/b with 700r4 and 3.31, my seat of the pants feeling is for my combo 3.55 would be better. Question though, if you drop lower than the 3.73, will you need a new carrier? rick schaefer http://members.home.net/jimmy4/rick1972elky.html http://chevelles.com/showroom/ricks%20motor%20-L On Wed, 23 Jan 2002 10:46:29 EST [EMAIL PROTECTED] writes: > > Replies to this message are sent to The Chevelle Mailing List > ------------------------------------------------------------ > > I need a consensus here.
