Hi I have some questions on the 472-500ci engines. I need to know what years & models used the mid-sump or rear sump oil pan (im putting it in a 41 ford coupe) also how does the front crank hub come off all of my manuals i have say to use tool# such & such i have no experiance only with sb chevys, all of my pullers the threaded shafts are to big to fit in side of the crank hub if thats how they come off .........thanks darrell

 

429,472,& 500 cad engines are front -Eldo, towards the front everything else. Late 70s 425 and 6.0l(368) should be rear sump.

Balancer - Take pulley off, Cadillac did not used bolt to retain balancer till late 80s-early 90s. You can use bolt grip type puller to remove it, but you need something to protect end of crank. To install it, balancer installer is recommend over board and a hammer. Use 1962 balancer bolt and torque to 120 ft-lb,then remove bolt and install cork. I think bolt is 9/16 NF about 1 1/4 long

 

Thanks for all the great info this really helps. here in nebraska we dont have huge salvage yards most of them only keep the latest years(kind of a supply & demand thing)Its not every day they get calls for 70s parts I can get after market but just trying to save some $ and half the fun is chasing parts sometimes?? I have been away from the car hobby for about 10 years, so have lost a lot of contacts & info as to where the parts & cars are at thanks again

 

The world changed in those 10 years. There are many more salvage yards at your disposal.
It is called internet shopping.

the sky is the limit.
