Author	Topic: 429 -4v Question
bobbyford72 Journeyman Posts: 10 From: new jersey Registered: Nov 2000	posted 05-22-2001 10:08 AM If a 72' 400m is replaced with a '71 429-4v, will the exhaust pipes bolt right up to the 429 exhaust manifold? I am planning on pulling my 400m out of my LTD and installing a 429 out of a LTD. I have not compared the exhaust manifolds yet. Any help would be appreciated. IP: Logged

My advice, find a parts car. In typical ford fashion, practically anything that can be different, is. I remember replacing motor mounts, throttle cable, having a custom exhaust made... and a buncha' other stuff I can't remember right now. A parts car will make all the difference. A lot of those big cars had 460's, so it shouldn't be too hard. Back then, the junkyards were littered with them. I purchased his running 460 complete (w/D0VE heads) for the grand sum of $125, and didn't have to even pull a valve cover. Good Luck! ------------------ Mike Burch 66 mustang real street 302 4-speed 289 heads 10.63 @ 129.3 http://www.geocities.com/motorcitymustang/cmml/cmml_mburch.html http://www.fortunecity.com/silverstone/healey/367 IP: Logged

The motor mounts will probably be different. I doubt that the exhaust pipes will line up. Your accessory brackets will not interchange. I replaced a 400 with a 460 in a '78 F-150. ------------------ Tracy M&M #245 1956 F-100 Panel w/460 (3.70 9" for Saturday night, 2.75 for road trips) 1966 F-100 SWB w/351C (3.25 pos) Music City F-100's, 1966 GT-350 S/C (2.78 1st & 3.70 TracLok 9") Music City Mustang Club Don't focus on the destination....make the JOURNEY the adventure Visit my Web site: DidgeyTrucker's Website IP: Logged
bobbyford72 Journeyman Posts: 10 From: new jersey Registered: Nov 2000	posted 05-23-2001 10:22 AM Thanks alot guys for the info. I have a few more questions. Replacing motor mounts. Does this mean the lower mount on the frame? Is this mount on the frame welded or bolted? If bolted, a simple bolt up swap from donor car? Also, does anyone know which set of headers can be used in this application? The car is a 1972 Ford LTD convertible with transplanted 1971 429-4v. Thanks again. IP: Logged
