I recently installed a 700R4 in my 68 BB Camaro. I am very happy with the result. Before the swap I was constantly looking for another gear with the 400T and 373 12 bolt. Anyway here's some of the nuts and bolts of it. I bought a shifter converter kit from Siftworks. My understanding is the stock set up will work, you just can't pull the trans into 1st manually. I bought the crossmember from BTO. Some will say it's overpriced, I didn't want to cut up my original, so if I was buying anyway, that's what I bought. On my offset BB application , all the holes needed slotted a fair amount. On a centered small block I think it would be a drop in affair. Whatever crossmember you use, make sure there is no metal to metal contact, you will not like the result( ask me how I know). I ordered a new heavy duty driveshaft Denny's driveshaft to fit my application. There are other ways to do, but I got on the phone and 2 weeks later a perfect drivshaft showed up at my door, and my original is still intact, nuff said. My trans is a TCI streetfighter which I found locally on EBAY. It came with a lock up wiring kit which includes a vaccum switch. I can manually lock the tc in second and third and it locks on it's own in OD. Thes can be bought from TCI if you're interested. Not sure if a vac switch is really needed, I think I might prefer full manual control of the lock up. Torque converter is a Pro Torque 2800 stall. One of the really nice things with this set up is you can use a fairly slippy torque converter, but with a flip of a switch it locks and doesn't mean a thing. Nice!! Overall I am very happy with the swap. If I would have built a trans or had one shipped in I probally would have gone with a 2004R, but at my power level the local 700 R4 fit the bill. I used a Holley TV cable bracket, a geometry corrector bracket from Sonnax on my Holley carb and it works fine.
