seeing as we're on the subject - I have a 408 (300 RWHP), a 727 - full manual kit with a 5k spragless converter backed by 4.10's - 305/15's - I want to "back it off" some to make it more street friendly without loosing too much performance.. for now the 4.10's stay - I am thinking 3800ish on the stall...? yay, nay?
