Your description is pretty broad and vague so I will generalize a set up or two that will fit most anybody’s “Hot set up.” The one problem is the torque converter. You need to know a lot about the car and engine to get a decent one and know everything for a great one.
Basic level upgrade from Hwy. gears;
3.21 - 3.55 gears, 2200 - 2500 stall
(Generally up to 230@.050 for a cam)
Mild hot street;
3.55 - 3.91 gears, 2500+ stall
(Generally a cam from 230@.050 - 240@.050)
Hot street;
4.10 - 4.30 gear, 3000 or better stall
(Generally a cam of 242@.050 and better)
This is very general and highly flexible completely dependent on the build and intended useage. However, if your new at this, you can follow the above general parameters and have an excellent performer.
