429 Engine? ID Help

Postby tschmitt » Wed Sep 23, 2009 6:10 pm

I just picked up an old Cadillac engine that I thought was a 68 472 but turns out to be out of a 67. The numbers on the block are 1482586 and the intake numbers are A318 P2A 1477387 I believe. All the brackets and pulleys are on it as are both manifolds. I read the 429 and 390 were not good engines to run so I will be parting this thing out. I will be taking it apart and taking pics of everything for sale. Anyone interested in some parts let me know. There isnt a carb for it though, wasnt on it when I got it. Been in a barn the whole time. Got it for free. Let me know what I can junk or if any of you want to buy some parts from it.

There may be some parts that will bring some money.  You can tell if it a 1967 by the intake, if it is a Q-jet flange (spreadbore) it will be a 1967.  If the pan is a rear sump with only one front motor mount in the middle it from an Eldorado.  If it has a front sump and two mounts it's from a deville.

The 1967 has one year only heads and if you sell them then sell the rockers with them.  Some like to convert to the Q-jet so the intake will sell.  Also the exhaust manifolds will sell if they are uncracked but you need to know if it is an Eldorado or a DeVille.  The front cover will sell also because they tend to rot over time.

Be careful on your prices and don't give the stuff away.

Other places to advertise is,

http://www.cadillaclasalleclub.org/forum/index.php and

http://www.modifiedcadillac.org/forum/index.php

since both of these forums have more owners of older cars.

Thanks alot Ted. The intake is a 4 barrel intake that had a Carter carb on it but the guy didnt have it. So im guessing now that its a 66. It is a front sump so its from a Deville. I took the valve covers off and the rocker set up is about as clean my 500 I just bought. The manifolds are uncracked from what I can tell but im having a hard time on unbolting a couple of bolts of the block. I read the article here about getting them off without stripping or breaking them and ive tried a few of techniques, no luck so far. It also has the torque converter with it, not sure if its worth any money though, I still got take it off. Ill take some pics in a lil bit.

Yes they did not make a Eldo till 67.  Go ahead and break off the bolts, not worth the trouble not to.  I think the exhaust manifolds are the same from 65-67 but not 100%.  I do know they are ugly and I really wonder how a 429 could breath out of them.  The TC should be a switch pitch but I do not know if they are worth anything since they are the large size.

ts,

Yes, the convertor is worth $ if it's clean inside. Should be a 13" s-p.

Just to be clear, they didn't make a front drive Eldorado until 1967.
My aunts used to come up to me at weddings, poking me in the ribs and cackling, telling me, 'You're next.' They stopped after I started doing the same thing to them at funerals.

The thing where he said the 67 was a 1 year head....  The 67 head used the T pedestal rocker setup that the 472/500 was about to use, perhaps some early testing?  The previous motors used a more typical shaft rocker setup.  Thats why ted said to sell the rockers with the heads.
