It seems to me that you have a strange engine: the cast number is for a 1959 to 62 engine block. The number 26K....is for a 1962 engine with air conditioning. But 1962 cars had only one 4-barrel carb!
The numbers on the carbs (2372S & 2373S)are from 1956...
Unfortunately, I have no list for the intake manifold casting.

You should see another number (the VIN) on the block: if its a 62 engine, its located on the lower LH side, near the oil pan, between two welch plugs. Engines from 1959 to 1962 had a 390 CID.
Production number: a lot...

Jan,

The block number 1473267 is for a 1963 Cadillac 390.

For the casting numbers for the intake Ive found that these are really screwed up. I have a couple of books but they seem to be incorrect.

Anyway, the 56 carbs are a good indication that this a 56 intake.

Good Luck

Everything that Ive read states that they moved the dizzy up front for easier access in 1963 when they retooled the 390.

Gday Jerry,

They did move the Dizzy to the front on the 63 390, but the engine referred to in the first place was a 62, so that will have the Dizzy at the rear.

HI ALL, John Washburn said that block casting number is 1963, and that one salvage car website (forgot the name) said the same thing, is it possible that some of the 1962 engines had this casting number or that some of the 1963 engines had the dizzy in the rear?? Im thoroughly confused as to what engine I own...

Thanks for all the info guys!

The dual quad manifold that you have I think is from a 1956 cadillac elderado with a 365 ci. motor.The reason I know this is that I found the same manifold with the same numbers 1464580 stamped into it. found this out searching the net .The info came from The carburator shop .llc.I've been tring to find it again to verify further.

 I'm not big on the numbers, but the last year Cadillac used a dual quad manifold was 1957, so no matter the number, it would not be any later than that.

 The 1963 engine was heavily re-engineered over the 1962 version. Not only was the distributor moved to the front, but it also had an external oil pump mounted in an aluminum front housing.

 Manifolds, however, could be interchanged still between the earlier 331/365/390 engines to the later 390. Likely what has happened here is someone had put a mid 50's dual quad set up on a 1963 390.

 It would be helpful if you could post some pictures.

I always thought it looked like a stretched rover or Jensen. Not unattractive but not anything special either.

That is funny as hell. I was on two boards at the same time and posted to this one by mistake. When I went back to the other one I didn't see my post and figured it vanished in the ether of cyber-space. HA!

I redid my post on the other one and just discovered my original missing post. I did swill down a bunch of beers at the NASCAR race today so maybe Stampie has it right!
