Can any one tell me if this will fit a nail Buick Super-Turbine 400 Fits Riviera, Wildcat and Skylark GS Bolts up to 401 and 425 Buick Wedge Chamber engines 1964, 1965 and 1966 Posted from the TJJ App for iPhone & iPad
Best guy to help you put this together is Russ he knows nailheads like the back of his hand the web site is http://nailheadbuick.com You can also call him 530-272-1564. Kevin
You will have to put an adapter bushing in the end of the crank for the torque converter to center in and you will need the right flexplate for the trans. Also you will need a starter with the right nose piece on it. The dynaflow starter is longer.
Should bolt to any nailhead 57-66, but 57-63 will need the crank adapter bushing. BTW: If this is a 64 transmission it will only have 5 detents, as it is a single range 400. PRNDL. But it still is a 3 speed box, no intermediate range to pick, just L and D.
Can I put a standard 400 valve body on to make it shift like a normal 400 Posted from the TJJ App for iPhone & iPad
No, morphadite pattern. You won't find valve body gaskets either. At least I couldn't 15 years ago, last time I had one in the shop. Put it together with out, really stoned all the surfaces, dynoed fine, customer never complained. Leave it in D and enjoy.
Valve body gaskets for the 1964 ST400 are available from Fatsco Transmission Parts NJ 800 524-0485 www.fatsco.com
Try and hook up the Switch Pitch two stall speed torque converter. B&M makes one I think, great find now a 401 or a 425 to spin it
I just had one rebuilt for my 63 Riv. Rebuild with a new torque converter 65-riv trans $980.00 But, in order to get it to work correctly, I had to get quite a few pieces. 65- gas pedal assembly with with electrical for the trans, 65- front and rear driveshafts, 65 Crossmember, 65 posi rear end, 65 shifter (Which is quite different than 63 or 64) A 65 trans is longer. Also found out you cant mix the driveshafts because the lengths are different. 65 rear also uses a flange which is different. 63, 64, and 65 where all quite different from each other. I would search out the parts for that year and see if you can adapt them. We're doing the swap at the end of June. I'll post pictures of the whole process. I hope this helps. Dave
