[QUOTE="Hoosier Daddy, post: 14344, member: 61"] As a coincidence, in my '81 standard, I found a replacemment engine is an '83 which has slightly different gearing mated to my '81's original final drive... I have done some research and found not only the trans gear ratios are different between the two but also the secondary reduction and the final drive specs as well. Lower 1st gear (2.642 compared to 2.500), YEAH! Same 2nd (1.667) Taller 3rd (1.20 vs 1.286) Taller 4th (1.00 vs 1.065) And taller overdrive 5th (0.829 vs 0.909) My '81s final drive is not quite as low as an '83s this engine was originally mated to (3.091 vs 3.10) .... Now figure in the secondary reduction within the engine to trans connection on an '83 (0.897 vs 0.973). That lower first and the loss of weight will help me out of the hole at the stop lights, but you can see she's a hybrid suited for top end out on the highway... at least I shouldn't be looking for 6th gear!
