U joints recommendations
 

69 Camaro.

Don't car about originality on these. Mostly don't want breakage.

Will be driven hard.

Won't side step the clutch, but will dump it from time to time with drag radials.

U joint recommendations?

Moog non-greasable 269?

Thanks for any help.

Non greasable would be the strongest. I had no problems using NAPA's u-joint with my 470 bb. And i don't baby it [img]<<GRAEMLIN_URL>>/haha.gif[/img]

I use these <span style="font-weight: bold">Lakewood</span> U joints on my BB Nova. Haven't broke them yet with Quick-times and a 4 speed, and I'm not easy at <span style="font-weight: bold">all</span> with it....

Re: U joints recommendations
 

This is not a weak link. I agree with non-greasable to be stronger.

Good point.

So... what is your opinion regarding what is likely to break first.

For sake of discussion:

Modified small block about 425 to 450 horse, about 400 torque
factory z clutch set up (flywheel pp and disc all factory type)
unmodified m21 trans
factory drive shaft
factory eaton 4 series posi carrier
richmond 4.10 gears
drag radials

Re: U joints recommendations
 

The trans definitely if it doesn't have a 12 bolt. Even a steel bearing center plate would make a difference.....

Re: U joints recommendations
 

Those 12-bolt spider gears don't like sticky tires either.

x2. I have been running the NAPA Precision Super Strength U joints for years in my cars, and mine don't get babied either on the track or on the street. I have never had a failure.

Agreed. There's a reason all these Muncies are MIA. The aluminum case allows the gear to spread, moving the tooth contact area into areas that cannot handle the load.
It will probably handle non-race usage, but it's being pushed.
