Hot Rods Cadillac Engines, post a pic of your 331,365, 390.

I am always wanting to see pics of other guys Caddy power plants. So post away!! Mine is in pieces, so it's not really worthy.

 

My Caddy , ain' t pretty but she's fast !

 

331cid

 

Still deciding on a future for my 365.
I just got it mounted in an engine running stand so I hope to hear it run soon.
They sure are a wide motor across the shoulders...

 

Looks like poo now, just starting the teardown of my '55 331.

 

Keep em coming!!

 

Not mine but I've always liked Caddys!
My first exposure was around 1956, my cousins friend had a 53 Stude with a Caddy motor. A rubber burning son of a gun!

 

Interesting headers on the triple offyed intake engine.The one with the red leads.
A lot of work gone into the mounting flange bolt areas,look like s/steel also

 

Mine, '57. Ron

 

Nice. Any better pics of your pcv setup?

 

I found this one on CL I was thinking about going to look at this weekend. Deal or no deal?????

From what you have shown, it looks to be a good deal.

 

What is the preferred fuel pump to use on these engines???
I think mine is a 1957.

 

This ones a later 49 331,if it’s a 49. the first ones had minor changes after I think 16 weeks.

 

Very cool pictures guys!!!
I love this early morning eye candy.....

 

57 365,A long way to go yet,

 

I have been advised that rebuild parts for these engines is hard to find and expensive. I agree with the expensive part but it looks like Kanter, Egge, and even sources on ebay (Falcon) have basic. master, and deluxe overhaul kits kits available. Have any of you Caddy guys had trouble getting parts such as pistons, rings, valves, guides, etc.?

 

The pistons are pretty much crap, but most of the gasket sets are decent. I have talked to a lot of the piston mfg and they are happy to build a set of custom forged aluminum slugs. The price tag is around $800-1000.

Isky, Howards, Comp and Steve Long still grinds cams for them. Just make sure the cores are available. Apparently there is one supplier of Cadillac cam cores.

Here's a thread I started that has a lot of other threads covering Caddys imbedded.

Piston rings on a 4.000 caddy are the same as 4.000 327 chevy . Chevy valves can be machined to fit in caddy , worn valve guides can be knurled to specs. I used 327 vette solid lifters in my caddy with Smith adjustable push rods .

 

Here was my original 331 at home in the 51 Cadillac that the factory installed it in.

 

Nice to see all the weight being put to good use.
Mine is a throw back with Isky roller, Jahns, Mallory Magspark, early shinny stuff with the exception of the O'Brian filter cover. T-5 makes long trips fun at 22mpg.[

 

Looks like it was made for it....

 

Whose tranny adapter did you use?

 

Here is one I built a few years ago!

 

To answer Roothaug, I used an adapter from Bentsen Transission Center, Ham Lake, MN 55304. 1-763-767-4480. Comes with hi torque starter. Also used a GM truck bellhousing with the throwout arm on the passenger side with a hydraulic slave cylinder so I could use the stock 1940 or so brake pedal assy. Bellhousing 15562385, clutch slave 15616089, fork 12385352, TO bearing 15613306

 

This should be enough to figure it out. Ron

 

Interesting. I'll have to refer to this when I get that far.
