Gear Vendors is undoubtedly good, but if the 700R4 will make a decent setup for an early B body, I have the trans already. Not too concerned about strength as I had well over 100,000 miles on the original 700R4 before getting it rebuilt. Absolutely no problems. Besides, it is winter time, and I am looking for a "winter project". Sure would like to hear from anyone who tried this swap already.
