When you get the ST400 w/ switch pitch, be sure you get a carburetor to go with it, and all the linkages, brackets, and wiring.
Not when it's an extra $850 for an adapter :bla: . Cheryl, I think he was refering to a '64 ST400 vs a '65/'66 ST400. But, if he was refering to a 3spd manual, I'd go that route too :3gears: .
Before we get carried away with the wiring, let us know about the 401 build. Is it stock and will it remain so? The reason I ask is that at the low stall setting, the variable pitch torque converter tends to have a bit less stall than a typical stock fixed pitch converter, so at low stall a decent idle may be difficult to manage if you are running a hotter camshaft. In the original application, the variable pitch setup energizes the converter to high stall whenever the throttle is closed. If you're running a stock 401 you may not need this feature. We can get into the detent (kickdown or passing gear) and high-stall wiring after we get some feedback. Devon
Jim Burek at PAE Enterprises is among the world's elite with respect to Buick engines and transmissions. He can build you a converter with what ever lo and hi stall speeds you want. The last number I have for his is 915-855-6009.
