Here's the results of our first pass last night. Put me back on the trailer after snapping the pinion pulling second. Still ran an 8 at 35mph.
nothing against a 9 inch but thats why i like the 8.8, the pinion diameter is the same as a dana 60...
I think it's FMS but I'm not sure. I got the chunk out of the junk yard four years ago, 4.10 spool been hammering it with 4 to 5k launches on the brake since. It was very good to me. Although it's cost me $190 for a new drive shaft.
