Got rear end all together and in the car old 8" had a 3.50 gear with the new 9" it's got 4.11 have to go to the track this week and try it out
Looking Good! That'll be one less thing to worry about. Is your driveshaft going to be ok to use? Same U-joints and all?
Yea I used a ford motor sports aluminum one for the fox body mustang (m-4602-g) just take the flange off the back and change the u joint to a 1350
Sweet...looks like you've got your bases covered. Keep us updated on new times with the lower gear...very curious myself.
Nice! Top of 3rd gear.. here you come! I'd be amazed if you don't drop a full half second or better off your times.
I am running a 9 inch with 3.89 . I was told that 9 inch was harder to turn than 8 inch. I was thinking of going to use a 8 inch with 411 gears .I have friend is going to a 8.8 because it turn easier. He is building a stocker I have a 349 c4 3000 tci best et 11.94 115 mpr 1/4
The spline count is not the greatest issue.. material type is. Now plenty of premium steel shafts being made for the C4.
