3600+ stall/cooler.
If you aren't going very far with the car then do the gears. If you are save up for a stronger rear end with better gears instead.
Stall needs a tune in obd1.
And "ripping most anything on the road" doesn't give us a good indication of how fast you wanna go as that can be open to interpretation. 10s? 11s? 450whp? Etc. etc.
