The center of the most common truck pan, the 5 quart pan is about 4".  The deepest part is about 5 5/8"
The HD 6 quart pan is about 4 5/8" at the center and 6 3/8" at the deepest.

If you are asking me, the deepest part of the truck pan isn't 6" deep, so I would say you would be alright.  I added an inch and a half to my modified pan and it only measures 7".

Are you able to measure the lowest point of the middle section on the Truck pan ? I need it to be less than 6" deep so my Tie will not hit it. This will tell me weather I purchase one or not.

Thanks,

here's some pictures of what I had to do to get the truck pan to fit with an aftermarket crossmember. It's a 292 using the stock motor mounts on a 56 F100 frame. The crossmember is from a Mustang II suspension.
 

 

my truck pan is the same as the centre picture from ted. it has the baffle shown in picture. it came from a f3 with tulip style exhaust with high mount fan front cover. dip stick centre of block. 
will it fit in a bird,it did in my case but never had to remove the pan and that was25years ago.i do remember not having the water pump spacer or correct front damper. had to make gen mounts and mod pulleys .i do remember it was not easy putting a non bird engine in due to differences in the front,i did use a f1 front cover and mount(with ought high mount fan place

John. Minimum depth would be 1¼“. That should just barely clear for a 312 stroke with ECZ rods. Give yourself an extra ¼“ to be on the safe side.

Ted -- I believe I am going to have to modify the front of the rear sump oil pan to fit the 292 into my '55 pickup to clear the cross member on my new suspension. What is the minimum depth of the pan to clear the crank?

Thanks

If you are tryin' to add volume to your T bird oil pan it pretty easy to add about 1" to the depth of sump. I have done this and will post a pic when I get to the computer where the pic resides. If you do it you will need to drop the right hand arm of the steering linkage so that the linkage will drop out of the way as the pan goes past it when the engine is inserted in the chassis. For me dropping the linkage is necessary whether installing with or without the trany.

As Gary says, the HD truck pan is closest to the T bird pan but to use one you would need to section something out of the front of the pan because there is not a lot of space between the x member and the front of the stock T bird pan. A Show T bird would loose points for sure with a modified HD truck pan, because it is not otherwise identical to the stock pan even if the welds are hidden, (but the engine wouldn't care!)

They say, the fastest way to the brain is through the eyes, Ted is the master. Thanks Ted for all your time and effort.

Love it Ted, a picture is worth a thousand words!
