Ok. . . I've got a THM-200 3 speed auto and i was wonderin what would i have to get/do to convert mine over to a 4 speed manual?
It would have to be an olds tranny or a chevy w/ dual bolt patterns. What would i have to do? Whats a good 4 speed?

It will have to be a BOP part. They are getting pretty hard to find but I have to believe with a will there is a way. Start looking in Buick, Olds and Pontiac websites and salvage yards. Be prepared to pay not to say you might not get lucky.

If it is a good core it is worth the money and you can build a the 350 to handle quite a bit as I found out.
