3800 with a clutch!
Also, I can't seem to make this intermediate shaft work. Just not going to happen.
Sure, I could use an output shaft from a 4t65e with a bearing on it, but that's much more work than the 32" shaft I already have, just needs one end re-splined. So, going with the long cv shaft option after all. That's going to take a few weeks before I can get that done, so I'll move on to other parts in the mean time.
