stock red stripe ratios vs 309 gear set.

race red stripe--- 2.65 1.64 1.19 1.00
309 gear set----- 3.09 1.92 1.40 1.00

The drop between 3rd and 4th is more of a concern than anything else, and for anything but full race application, that 309 set is a decent affordable option imo.
With todays slipper clutches, longevity should only be improved.
As stated by others, it depends on the package.
Dumping the clutch in anything weighing near 4000 lbs should be expected to have reduced life.
Add bite, hp and no clutch slippage and something will give.
