I have owned a 330, 390, 429, 472 and 500 cu in Cadillacs in my lifetime, but I could not help you with that question. The 67 Cadillac had the 429 and the 68 had the 472 with virtually the same body style. I think they both used the TH400 tranny. Check this board if you have not already, it covers the 500, 472, 425 and 368, but not the 429 from what I can see, but its possible that someone there has the knowledge you need:
