Jimmie, if the '65 Belevdere rearend you plan to upgrade is from the
so-to-be-440 powered wagon you list in your sig, a 741 case is not a good
choice to invest in. The pinion stem was not designed to support the torque
even a mild 440 will produce, especially in a 3900lb vehicle.
Furthermore, unless you have some good used gears or NOS gearsets, 741 ring
and pinions are unavilable and have zero aftermarket support. There is a
reason for this.
The Chrysler 8 3/4 guide penned by a person nicknamed Vaanth is essential
reading - Google it. It explains clearly the different cases and their
strengths and weaknesses. If you want to go for a sure-grip - which is a
great idea - I'd look for a 742 (my choice) or a later 489 case (biggest
pinion stem). Either of these will be more than adequate unless your 440 is a
really wild one.
Best Regards
Wakeman

Gary,
So this would change my 1-legged 741 on my '65 Belvedere into sure grip? Do I
leave my current high geared ring and pinion in. Would this then be the time
to get a lower geared rear end? What does this entail??
And finally How much?
Thanks again as always.
Take Care,
