I HAVE A 5.0 EFI + - 370 HP. I HAVE A TKO WITH 3:55 REAR END. AT 70MPH I'M TURNING ABOUT 2000 RPM. I HAVE TO DRIVE AROUND TOWN IN 4TH GEAR. I HAVE ALL THE POWER I NEED FOR HILLS. FOURTH OR 5TH GEAR NO PROBLEM. MY BUDDY MIKE HAS ABOUT THE SAME ENGINE IN HIS FFR, BUT HAS 3:73 GEARS. I THINK HE DOES A LOT BETTER AROUND TOWN.
NEXT TIME I'LL GO 3:73. 
SPRING FLING FOUR, I CAN WAIT!!
