70 turbo 400 cw code. what is the application

[dvss1]

I have a turbo 400. Tag reads 70-cw. 1590 and above that is 289. Only thing I could find it fits 402 and 350 in nova and camaro. I"m hoping it fits the 396 350 engine. I have a few pictures. Any help is appreciated.

Scarce trans..1970 L-78 Chevelle-Nova assembled after Oct.16th 1969.
1970 LT-1 Nova used it too,but I think your date is too early to consider it came out of one those.

Is there a con VIN# stamped into the driver side machined pad above the pan,to help determine what car it originally came in?

Also 70 Z28. First year for turbo 400 in the Z28

If it still has the original converter, it has a high stall speed. I think it's 2600rpm.

should be 6 lugs on the converter... shouldnt it be?

The CW coded TH400 will work fine behind the L34 motor...this a HD unit designed to work with the solid lifter big blocks. If you clean the case carefully you may find the letters CW printed in a pink color. These transmissions used the 6 lug convertor, hi-shift point governor and many other special internals.

The VIN is typically on the driver's side pan rail area...but, I have seen them on the bell housing on pass. side as well. As mentioned, given the date code, this could have only come from a Nova or Chevelle with L78.

Very cool part...good luck.
