Engine Swaps

[greg g]

We early mopar owners did a bit of sleuthing today. Here is what we found

51 Plymouth business coupe had a D42 block

40 Plymouth 2 dr sedan P26 engine with 40 carb and intake

52 Dodge meadowbrook D 42

49 Dodge Coronet conv ( owners says he was assured the engine was original) T 306 with gyromatic

36 Plymouth coupe P 12 engine.

39 plymouth sedan p15 engine

39 Plymouth truck p12 engine

my 46 Plymouth p26 engine but I nkow where my p15 engine is.

so only one had the correct block.

[BobT-47P15]

Nothing much new about that. Lots of these old Mopars seem to have had

engine transplants. My 47 P15 has a 1957 engine.

My 47 Chrysler has a 218 D40 Canadian Engine, I also own a C38S engine, which is the correct engine for my car, it has full flow oil filtration, but needs a rebuild.

[JerseyHarold]

My '51 Plymouth business coupe engine block is dated 1953 (no serial number; probably factory replacement) and the head is dated 1955 (or vice-versa).

My '52 Cambridge has a '57 230 in it, that came out of a '39 Dodge.

my 48 has a combine engine in it, with these motors it seems like it is cheaper to swap them out then rebuild them.

My '40 Dodge (D14) has a D24 engine! My late father-in-law did the swap in 1952.

My 53 Suburban has a 53 Plymouth motor but it previously lived in a 50 Plymouth buzzcoupe. I still have my original 53 motor on a stand, for a rainy day.

My D36 engine is now re-machined, and will be returning in its original spot....

Wow Phil that swap was done a while ago, any idea how many miles you have on that engine, what kind of condtion is it in.

I am contemplating doing the rear main seal and oil pan gasket on my 1951 D40 engine, but I am not real keen on pulling the trans and flywheel to do the seal, yuk, not a fun job, should have done it last year, when I did the rear frost plug...........Fred

[Reg Evans]

Only my 35 Dodge sedan has it's original engine.

My 38 Dodge bizzy coupe has a 52 Dodge 6.

My 42 Dodge bizzy coupe has a 48 Dodge 6.

it's original engine is going to be rebuilt one of these days.

My 49 Plym. Suburban has a 59 Dodge truck 6.

My 52 Dodge truck has a 50 Chrysler 251.

[55 Fargo]

Hey Reg, I figure you might have a likin for the flathead 6s. Do they all run?

[Reg Evans]

I do likum Fred and YES...they all run. Well, as of yesterday anyway. It's fairly early morning here now.

Fred,

If you do a search for my posts in 2005 and 2006 you will see the many trials and tribulations I had in getting this engine running well. I have no idea how many miles it has. It was a Chrysler rebuilt unit when installed in 1952, came off the road in 1956 and when I pulled it out of the field in 1968 the speedometer had been shot out (wife's cousins having fun). I did a valve job in about 1971. Currently a tired but well running engine :-)

Hi Phil, I hear you on the "trials and tribulations", I have had a few myself.

All is well at the moment with my engine, with the exception of the oil leak.

I have a spare engine in the wings from a combine, if my current engine goes south all of a sudden.

I really need to concentrate on body/paint now, I want to get all of the bodywork done,followed by paint.

Then chrome and interior, then I will maybe go back and play with any mechanical issues that still exist, hopefully I am not doing this backwards.................Fred

Dad's first family car was a '46 P-15 sedan that he bought while stationed at the Air Force base in Ft. Worth, circa 1953.

When Dad when to Texas DMV for his tags, the clerk informed him that his "new car" was a retired taxi-cab from Shreveport, Lousianna.

At any rate, Dad schlepped the family back & forth between Texas & Baltimore, and Rantoul, Ill, & Balto, and Macon, GA, and Balto, etc.

One trip home at Christmas, they had just gotten onto the PA T-Pike, near Pittsburgh, when Dad noticed there was no oil pressure. They pulled-off and checked the oil, and looked for any obvious signs of trouble. Finding none, they continued on their way, making it in to Balto, driving around for the week between X-mas & New Years, then driving it back to Ft. Worth, and around there for two more weeks before the engine finally seized.

Dad and a buddy towed the car out to a nearby salvage yard, bought a second-hand engine for $50, loosened-it up, then the yard owner used one of his wreckers to pull the "new" engine, and drop it in Dad's Plymouth...

They had P-15 from 1953 through 1957, finally trading it in on a brand-new '57 Rambler Cross-Country wagon, after Dad finished his hitch in the USAF...

So, there's one P-15 that had at least one engine swap...

My '41 De Soto has a "correct" S-8 engine, quite probably the original; everything else mechanical on the car has been factory original.

The 251 Spitfire I picked-up the other fall came out of a '39 Chrysler Royal, but the block code specifies '46-'48 Chrysler six (Windsor or Royal)...

I did discover the other day that what someone said about an actual

date on these engines is true.

As mentioned, it is down below the distributor just above the flange to

which the oil pan attaches. Just behind the hole where the oil filler

pipe goes. This one is 12-18-1954.

The problem about reading it is - its location, plus the fact it will

be painted over and perhaps covered with crud.
