    Looking for TH400 governor cores to experiment with, trying to develop a repeatable formula for various shift point RPM at defined levels of line pressure.. Can be from any year, make model but would appreciate a notation of what two letter trans code it was from if possible. I've been paying 10.00 each locally, PM me to discuss...

    Outstanding idea Rhett. I had planned on tweaking my shiftpoints as well and put one govenor aside. I also have a B&M Governor Recalibration Kit BMM-20248 $75 , on my Summit wishlist. Probably a good idea to keep the original unmolested. Jim

    Steve,
    Rhett appears ready to try his hand now, I will probably not have any results to share until next season (dtagstrip). Jim

    SOMEWHERE on this forum (I wrote it, but can never find it) I did a thread on my governor set up which was spot on 5300 shifts with stock th400 line pressure. I used 1 B&M spring and weight in that recipe, I want to duplicate it with all OEM weights and springs but I'm going to destroy a few in the process I know, hence the need for a few cores on the bench.......if you guys need a pretty good starting point, that thread shows just what I did.

    Bigpig455. Just found it. Be reading this tonight. Pot of coffee. No IPA’s tonight. It will be a good read.

    Rhett, in the future, if you are having difficulty finding an older post/ thread. Search google or another search engine for your topic and add v8buick.com to the search. Seems to work far better than the search engine on the website. Jim
