Well, I recently had the 904 I have rebuilt (Fresno) and asked the owner of the trans shop to install a shift kit. He said he does that anyway, so I just got his "regular" rebuild. It seems to shift very smoothly and very quickly, which I like. The strange thing about the rebuild is the shop gives 3 years or 50,000 mile warranty, which for me is unheard of (i expected something like a 6 month warranty).
Anyway, when I put together the "stockish" 340 I need to rebuild, it will replace the stock '72 318 which is in the car now with the 904. I guess the 340 will go in just the same as the 318, except for one of the motor mount brackets and one of the transmission to engine braces.
