Re: Sure Grip for sale

[Wakeman Massie <wakey@xxxxxxxxxxx>]

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
