Mechanical to Hydraulic lifters

I know the 4:10's aren't the best for the highway, but once I get the TR6060 in it will be awesome. As for when get it in I'm not sure.
The car should have 3:55's as stated and would knock the RPM's down but it will still need the overdrive.
I'd just rather hear the exhaust note instead of the motor!
