Rear sump 460 or 429
Well, I didn't do the rear sump mod when I put my 460 from a Lincoln into my pickup. Consequently, I banged up my oil pan badly enough that I leaked out my oil and believe I have spun a bearing. This is fine because the motor is getting tired anyway.
My question: are there any rear sump 460's or 429's that would be a direct drop in? I have a 1973 F100 Ranger that I have converted to the Duraspark II electronic ignition (thanks to those of you who helped with that). It will be bolted to a C6. Yes, the truck is 4x4. The motor that is currently in it is from a 1975 Lincoln Continental. I really don't want to get crazy with changing motor mounts, headers, etc. If there any such of these animals out there, what years and in what vehicles?
Thanks! Shane

the 80s model 460s from vans, or 4x4s has the rear sump pan, but you can buy the pans, and pickups from ford new still so it's not a big issue. Only other thing is if you switch from a front to rear sump pan you will also need the rear sump oil pump.
Also keep the flexplate with the motor, the 79 and later motors are external balance, the earlier motors are internal so the flexplates are not a direct swap (although they will bolt on, but it will affect the balance adversely)

Rear sump 429/460
I have read where the front sump, to rear sump pan conversion requires you to purchase the heavier model pump and also the longer one piece pickup tube and screen which are bolted to the pump body
I have not been able to find any information showing the differences between these two pumps in gallons per minute flow, or in oil pressure
seems like I did read where the heavier pump had different gears and a higher setting inside the spring loaded valve assembly for bypass though
it all make sense to me that it would need more power because the oil has to travel around 14” farther before entering the galley into the filter
I have also read where this can be a weak area, causing damage to the cam drive and other components if one decides to go to a certain higher level of horsepower that these parts might not deal with well
The next choice to handle these ponies would be an external wet or dry sump equation and more money out of your pocket, but by doing so, also adds to the horsepower in several areas
wanting to head that direction for big hp is great, but if you have no choice due to clearance under the hood, then you will be where I am with my current build
These systems are very complex, and can’t always be swapped because they are built different for each engine family
Is there anyone in this group that can share some knowledge on this subject, I could sure use some input
