I'm thinking of going with this 289 motor (http://www.proformanceunlimited.com/289_350dropAL.html) and need a transmission to go along with it. Is a rebuilt/remanufactured T-5 going to be strong enough or do I need to go with a Tremec TKO 500/600? Also, is there an ideal gear ratio setup for daily driving but can still have fun with? I have a modified T-5 in my Mustang geared like such...1) 3.39 2) 2.00 3) 1.33 4) 1.00 5) 0.74 F/D) 3.73, and it isn't ideal for cruising but winds up and screws off the line.
