What I have is a 8-3/4 with 355 gears
Running a 340 (probably 360 horse) through a built 904 with a 2800 stall...
An old friend ran a 8-3/4 with slicks behind a 440 RB in the mid to low 10's for years.Thanks guys!! Sorry I'm so green!
This is all great info! I feel much better..
I just put fresh u joints in and the shaft is sound (far as I can tell).
"IF" your new u-joints have grease fittings, are they in the cap or in between the caps? If they are in between the caps (in the u-joint body), they should be "in compression" - (Slip yoke ears should be turning towards the fitting and rear driveshaft yoke ears should too.)
Hope that makes sense. Torque should be compressing the joint where the grease fitting is instead of trying to spread it where it's the weakest, at the grease fitting hole.
My grease fittings are in the cap. I was told those were the stronger of the two? Are the cap ones better then the ones with the grease fittings in the middle of the u-joint?
Do they also make a crossover U-joint?IMO the best u-joints are solid, pre-greased by Spicer.
