Is it true?

[Renato]

I read somewhere the 50's Cadillac has airplane engine. It means the steel engine block, and parts the same quality as they used for airplanes. It it true?

My Auburn has a lycoming engine in it.
I also had a PA-14 (Piper 4 place ) Airplane that uses the lycoming engines

Cadillac automotive engines were cast iron until the Northstar in the 1990s. Most aircraft engine blocks are aluminum alloy. What you heard sounds like an urban legend.


Cadillac flathead automotive 346 ci engines - that is, up to 1948 - were used in light tanks during WWII with few modifications.

During the same period, Cadillac has produced mechanical parts for Allison V-12 engines, used on Lockheed P-38s or Curtiss P-40s aircrafts. But never manufactured aircraft engine blocks or complete engines.

Thank you the correct answer.

I believe only Oldsmobile had aerodynamic engines with their rocket 88 and rocket 98 engines.

Just a clarification: Cadillac engines were cast iron until the HT 4100 in 1982 volume models.

The Cadillac cast iron 368 remained in production until the 1984 model year in the Limousine & Commercial Chassis models only. The Limousine had the 368  V-8-6-4 DFI; the 368 4bbl version was used in Commercial Chassis.

They did use 2 Buick 425 'Wildcat' engines to start the SR-71...

And Packard built the Rolls Royce Merlin under license for the P-51 C & D models. That engine kicked the sh!t out of the Allison engines (used in the original P-51 B models) every which way.

I do seem to recall Cadillac touting their engine machining tolerances were of "aircraft quality".  Can't recall if it was in an ad or some other promotional piece.

That was mentioned in Pride in the Possession.

I always thought that the Cadillac tank engines were neat due to the exhaust coming out on top of the head instead of the bottom. Saw one in a hot rod and it looked pretty cool with the really swoopy headers the guy built.

Yep--"Pride in the Possession"  where "only the (industrial) diamond dresses the wheel" to machine "precision Cadillac engine parts".

Ah, so this is what "Pride in the Possession"  means!
