E220-3.67/3.07 these gear ratios sound correct right?
Well the one in our 300E is a 3.07, well since the 300D has a 2.87 are there any others that are available? We need to go 2.7* to 2.87 if there are any 2.7* ones that are available, which models are they in? Only reason we want to run these gear ratios is cause the last 260E we had was revving high and didnt go anywhere and then threw a rod the rod. That could have been something else, but high revving around the track isnt good. And when we did some burnouts with the 300E in the dirt it feels like its loosing gearing right away we need to run these gears out longer. any info would be great this car is for dirt racing enduros so thats why we wanna change it if possible. also I am not going to run into problems of the output flanges being different lengths cause I dont feel like change halfshafts. thanks

I believe that (memory issues) 260E is 3.27, 300D is 2.65, and 300E is 3.07

I have one for sale, EDIT: 2.87 ratio from a W124 diesel (its not from the parts car in my signature). I purchased it a few years ago for my 87 300E but the project went in another direction (got a 5 spd. instead). It’s been sitting in the shop taking up space ever since. It has an ABS sensor (not for ASR). $125 delivered to your door in the 48USA, Paypal or postal money order. Size, flanges, pinion yoke, and mounting are exactly the same as a 3.07 unit in an 88 300E. Let me know if interested.

I edited what I have, also should have edited my memory: Remove the 2.65, replace with 2.87 ratio
Speedo reading comes off the transmission, will not be accurate if the differential ratio changes from stock.
