BodybyFisher Posted September 1, 2018 Report Share Posted September 1, 2018 4 hours ago, Lance Johnson said: Bobbybyfisher. You said 472? ? I am NOT sure what you mean. The new TurboHydramatic FWD transmission that fit the 1968 472 came out in 1967. In order for the 429 to fit the new tranny bell housing, an adapter was used, do you understand? So, if you had a 67 Eldo with the 68 tranny, it would be easy to swap a 472 into the 67 but that isn't your circumstance. Removing the adapter, should allow it to fit the TH400 Please post questions as questions not doubts or confusion. Ask for clarification. This is a difficult medium for effective communication especially on a smart phone where being concise is best to avoid fat fingering spelling errors. @Lance Johnson.

Yes you were correct barczy01, the research I did late last night disclosed that the 429 in a FWD configuration may have a different oil pan, and using the pan for the RWD 429 solves that. I am searching for one now 750 CFM wow Pre-1995 - DTC codes OBD1 >> 1996 and newer - DTC codes OBD2 >> https://www.obd-codes.com/trouble_codes/gm/obd_codes.htm How to check for codes Caddyinfo How To Technical Archive >> http://www.caddyinfo.com/wordpress/cadillac-how-to-faq/ Cadillac History & Specifications Year by Year http://www.motorera.com/cadillac/index.htm Link to comment Share on other sites More sharing options...

Bruce Nunnally Posted September 1, 2018 Report Share Posted September 1, 2018 interesting quote here: Quote Front wheel drive The TH425 front-drive automatic transaxle also fits these engines as used in the Eldorado, although a special dual-sump oil pan and pickup are used with these transmissions due to the required half shaft clearance. Any RWD engine can be converted to FWD and vice versa if the proper oil pan and pickup are used, although two of the main cap bolts must be removed and swapped for studs with standoffs to mount the pickup bracket. Read more: https://www.crankshaftcoalition.com/wiki/Cadillac_engine_knowledge But again, I keep thinking that the powertrain in the 67 Deville will have most of the swap parts needed. My impression is the 65-67 had a 'new' transmission bolt pattern, and the engine came with an adapter ring to work with the stock 'new' transmission. However, both cars are 67 so again should be similar. Bruce 2023 Cadillac CT4-V Blackwing Follow me on: Twitter Instagram Youtube Link to comment Share on other sites More sharing options...

OldCadTech Posted September 11, 2018 Report Share Posted September 11, 2018 The bad engine comes out, swap oil pans if new crate engine even has an oil pan. install new oil pump and pickup tube. The transmission bolt pattern should be the same. THERE IS ALWAYS ENOUGH TIME TO DO THE JOB RIGHT - THERE IS NEVER ENOUGH TIME TO DO THE JOB AGAIN !!!
