Anything you do to get more speed and or slow the engine RPM's down is going to require a gear change of some sort.
T-5's and other overdrive units are going to require a change to an open driveline. Since you have a later engine with the stock
driveline, a later bellhousing will probably be needed as the trans mounting pattern is different. So add up the changes,
rear end assembly (6 lug to match the front), modified rear springs, bellhousing, transmission, driveshaft, and possibly mounts.
In my opinion any vehicle with a gear ratio in the 3:90 to 4:10 range needs something higher for better drive ability
but how to get there can be time consuming and costly.
