Industrial Hemi 354 Oil Pans

Has anyone had expierence with a 56 354 Cubic Inch Chrysler Industrial Hemi oil pan interchange? I have a stock pan with flat bottom and was wanting to put a rear sump from a p***enger car on the industrial motor (might be a Truck or Marine Engine also). I have a Hot Heads front cover with Small Block Chevrolet water pump.

Help or ideas appreciated.

 

Should just bolt right up. Use any chrysler pan 1955-1958.

Am I to understand you have the full length sump pan? My 56A 354 industrial has a rear sump.

 

Truck and industrial pans have a different bolt pattern.

 

The pan may be the 51-54 pattern. If the timing cover has a bolt @ 12 O'clock it's probaly the early pattern, if bolts @ 11 & 1 O'clock it's probably the 55-58 pattern.

 

Check with Big Al's Toy Box, they will likely have whatever you need.

 

I think a rumor was started by the Tex Smith book that all industrial engines are the same and have odd bolt paterns and different front covers. Not true. Some industrial hemis are almost indentical to p***enger cars motors and use the same equipment.

Get us a picture of the pan and rails.

 

Correct me if I am wrong, this picture confirms a Truck or Industrial motor/ oil pan. In order for a rear sump, I need to use this pan rails and have a rear sump pan built.

Thanks

 

I have one of those full length pans also and would like to know what all it fits.....

 

Here are some more pictures of the timing cover and oil pan .

 

My 56 354 IND has a rear sump oil pan on it...no problems!

OOPS!!! I just went and checked my pan and rail are different than yours!!!!

 

If those industrial pans aren't hard to come by (expensive), it shouldn't really be big deal to fab in a rear sump, should it?

 

Looking @ Tex's Smith's book, they show 2 normal pans & one like yours. Apparently most pans have bolt #2 or #3, but not both. Just looking @ it, I'd say a rear sump pan will use one or the other hole, & the other just won't be used.

 

You need a '51-54 car pan. They have rear sump and the right bolt pattern.
Are you sure your engine is a '56? What is the date code cast into the block? Is there anything stamped into the block just in front of the valley cover? Is/was there a metal tag attached to the block near the dipstick? The tag would look like this:

 

Block was a NOS replacement block from Canada. There are no numbers on the block to indicate year or type. It is a 354 and suppose to be 1956. But not 100% sure about the reliability of information.

Most people say it is a truck block, I thought truck, industrial, and marine were alike. Guess they are different

 

354 truck motors were avail. thru '58. Blocks usually have L8D7 designation.

 

Truck/industrial blocks, car blocks, and oil pans.

The difference in oil pan bolt patterns is with the front two holes on each side of the pan. The oil pan bolts to the lower corners of the front timing cover on all 51-54 car blocks and all truck/industrial blocks which used an iron timing chain cover. Some truck blocks have an extra set of threaded pan bolt holes near the front of each pan rail, and will accept a car pan.

Some of the later "Industrial" motors are car based. A tin timing chain cover will tell you.

All 51-54 car and all iron timing cover truck/industrial pans can be redrilled at the front of the rails so that they can be used on a car patterned block. This same pan used on a car block will leave you with two extra holes which were originally used to bolt the pan to the iron timing cover. Nothing to worry about.

Bascially, the difference in pans is a couple bolt holes near the front of the pan.

 

I also have a 354 truck engine. The pan is longer due to the bigger timing cover.I replaced timing cover with a hot heads piece for sbc water pump. Have an original center sump pan from a car, and a new rear sump pan from ebay. They are both shorter than the original full sump pan that came on the engine,but with the hot heads timing cover they match right up.
