what trans to use for road race?

9.3.7. AUTOMATIC TRANSMISSIONS AND HAND CONTROLS
Automatic transmissions are prohibited in all classes. However, the use of
alternative transmissions, including automatic transmissions, and/or hand
controls may be approved on a case-by-case basis. Such approval shall
be in writing from the Club Racing Technical Manager and shall be in the
driver’s possession at all competitions. (rules as of november)

Thanks. That's a perfectly clear answer to my earlier question.

A Schumacher kit is the tidiest way to get the 440 into the A-body. You'll need to know if the 440 is internally or externally balanced so you can select a flywheel. You'll also need a bellhousing that meets SCCA explosion requirements. In addition there is, of course, for a clutch and all that goes along with that. And the transmission of your choice. You may need a driveshaft depending on the transmission you are replacing.
