A tech from Blueprint thought the 3.08 would cause the 700r4 to downshift on a grade ... so, I may look for either an other complete rear differential at 3.55 rear end/gear set (pinion/ring?) if I can change the ones in the existing case.

Thanks BA ... look forward to hearing about it. Itíll warm-up long before I have to make a decision on ordering.

1961 Impala. 4 door. 283, turbo 350. Imron Midnight blue metallic with silver stripe.
