T5 in questions is out of a 1984 Ford Mustang with a 302 engine tag number 1352-065. The gear ratios are as follows 1st=2.95 , 2nd=1.94 , 3rd=1.34 , 4th=1.00 , 5th=0.63 , R=2.76. This T5 is a non world class unit so it will use 70W gear oil not dexron like the world class units.
I plan to put this in a 65 Coupe w/ a mildy built 289 and a 3:50 rear end gear? Mildly built means Preformer RMP package w/ stock heads and long tube headers, nothing more. Should I buy this one? Or look for a WorldClass w/ a different ratio? Thanks!
