I'm trying to decide if I should go with 4.56 or 4.88 gears and would like some input. Current details as follows. Eventually I will probably throw more motor at it though...

69 Dart
440 w/ 10.5:1 compression
906 Heads w/2.14 1.81 Valves
M1 Single Plane Intake or M1 Tunnel Ram
Hughes 246/252 555/572 Solid Cam
4 Speed
Dana 60
30/13.50/15 E.T Streets

This is a track car that will be driven on the street, however I am more concerned with track performance than how streetable it is.

Any input is appreciated. Thanks guys!
