I need to get my 12 bolt redone and was thinking of switching to 4.10's in stead of the 3.73 's that are in there now, but would like to know if there would be a big enough differance in my et's to warrant the change? Right now i'm running a 427 that does 12.1'[email protected] with a 1.67 60' any help you guys could give would be great thanks.

You might post your engine specs or dyno sheet so we'd know what the engine's capable of.
OH and current trap RPM's.

Trap rpm ? with an auto I pbly would not change unless you go 4.30 or 56's just how tall is your tire
