Turbo-Hydro 350 operation

bill dedman · 06-26-2007, 04:24 AM

I have a friend who wants to run a TH350 in a street car with no vacuum signal available for the modulator (he'll be using a mechanical, Hilborn port- injector that has no manifold, just 8 individual stacks.)

He searched for a mechanical modulator, unsuccessfully, and has decided to just put a full-manual valve body on it and run NO modulator. This is a street car, basically; a home-built street roadster.

I was asked to get some information for him RE: What is necessary to do to the transmission to allow the use of a full-manual valve body (but not a reverse-pattern.)

I know that the modulator will not function at all, and can be removed and the hole plugged. Someone else told me that there is a "kickdown cable" on these transmissions. I am an ignoramous when it comes to these TH350's and don't know why, if it had a modulator, ir would NEED a "kickfdown cable:, but I am asking... Does a TH350 HAVE a kickdown cable at all, and should it come off in the case of a full-manual (probably Turbo-Action) valve body being installed?

Should the governor be removed, since it won't be used any more?

Is there any other modification that should be performed during the installation of a full manual valve body?

ANY information will be greatly appreciated.

Thanks in advance...

Bill
