Clutch plays a big role. 4.56? Low rpm engine or street strip? If you can't hook the low gear and adapt the ratios to compensate, get a gear set that is easier to upgrade. Make sure the forst gear set is 33/15 and work with Scott at Jerico to pick the rest. If you plan on ramping up the car to handle the more traditional race ratios, it makes a difference. If you do it right, you can then change only main drive gears to go to a 3.19. If you pick some weird ones, it gets expensive because you have to choose a whole set.

Thanks for the replies, Its a 383 small block chevy. I will be shifting at 7200 and should be going through the traps about the same. Probably a 29x9 tire. Once its done If needed might go to 4.88. It will be a 4 link so hooking should not be a problem. Clutch will be a ram adjustable. I see a lot have the 3.08 1.93 1.34. If you go to a 3.19 what do you bring second and third to?
