Thought it was a 429. Apparently not. Retarded me! What to do now???

[Speach]

It is a 67 429 motor. My intake is off along with all of the head bolts. I have bent my pry bar trying to get them off. I have tried this along with a rubber hammer. No luck. I recently got heads off of a 472 without any real problem. This motor is not nearly as tough as the 472 so what can I do without damaging anything?

[The Tassie Devil (Bruce Reynolds)]

Use a flat bladed Screw Driver, of reasonable size and the thinner the angle the better, and carefully drive it between the head and the block, say in the front outside corner, and simply use the Screw Driver as a wedge.

This will lift the head, and not damage anything, as there are no damageable parts in this area.

It will just be the Gasket that is holding the head on.

Are you 100% sure all the head bolts are out?  Bending a pry bar is MAJOR.  I know that is going to sound silly to ask you but sometimes it helps to have a buddy or someone else suggest the obvious.  Ask me how I know :-)  BTW, there are 13 bolts per head. 

How about the water crossover pipe, have you removed that?

The other thing is... the heads are really heavy.  Maybe a few more taps with the rubber mallet and then grab a hold of the head by the springs to try and unseat it from the block.

Agree. Make sure you know how many bolts there should be and that all are out.
(been there too, though it was an intake manifold)

Trevor, 13 is a strange number. Got a picture for Speach showing the locations?

I think I remember finding those extra bolts when I took apart my 472.  I could have swore that I took all of them out but I am pretty sure that I dont have 13 bolts per a side out. It was a lae night last night so I will look again today for anything keeping them from coming off. Thanks guys. So I looked and cant find any other bolts. Just ten and they are all out. So I will be prying them off later. Now I am wondering? Should it have 13 bolts if the motor is a 67 429. I bought the motor from a guy who said it was. At first I thought  it wasn't until I learned that 67 had the rochester. It has a points dist, is smaller than a 472. Any thoughts?

If the motor you are talking about is the one in the picture, it's not a 429, but a 472/500.  If you are trying to get the heads off with the intake still in place, try taking the intake off and you will have a little better luck.

What engine did you post a picture of?

The one you are working on now?

[STDog]

Well, the felpro gude shows 17 head bolts.

(#7 on page 64)

And that matches with this picture of a '65 head.


A row of 4 bolts, a row of 5, then a row of 8.

The bolts that hold the rocker shafts are also head bolts (on the 429).  Make sure you get all those.

The 429 came with either a Carter OR a Rochester (not a Q-jet) in 65/66.  I think in '67 is was a Rochester only (and was a Q-jet).

Here is a picture from a factory shop manual for a 1967 429.  

ST and Mose are right, there are 17 bolts.  I didn't remember that the top row of 4 bolts for the rocker shafts go down into the block.  However, like Greg said, if the 429 you think you're working on is the one you posted a picture of... we have good or bad news for you depending on what you want your outcome to be    That engine isn't a 429.

Yup the motor I am working on is the one in the photo. I have already taken the intake as I previously said. This sucks because I was under the impression that it was a 67 429. I have a 72 472 and a 69 472 and this motor looks older than those. It must be a 68. I will find out after seeing the piston heads. I need to run the numbers as well. I should have done this already. When I went to get this motor I almost didnt get it because I thought it was a 472. Remembering that the 67 429 was a change over year pre 472, I thought well I drove all this way maybe it is a 67 429. I was thinking that the guy had it mixed up confusing the 67 car with the 68 as most people don't know how different the two are. So here I am. I bought this 66 Calais real cheap and got this motor for it. I was trying to stay away from a 472 due to from what I understand it is a pain in the ass to convert. Any thoughts? I know the 472 will really move this car. I am pretty resolute about doing only mild custom mod work keeping the car mostly original. I am an artist though and when I go to the Cadillac and Lasalle page,  I here many of them snob down at modified it just makes me want to go crazy on this car. Any suggestions about the swap? Know of someone in the south east who will trade a 67 427 for a 472? Thanks guys.

Mr.Speach,
Now that we seem to understand that the motor in your 67 is a 429 and the motor you bought is a 472 I have a question.  What do you want to do?  Is the motor in the car bad?  Are you ready to go through theeffort and expense to convert your '67 to a 472 (exhaust system, motor mounts, transmission issues, linkage issues, cooling system issues, etc., etc. etc.)?
Do you want to consider rebuilding your 429?  One step at a time please.

The '68 and '69 engines are the same.

Post the casting number form the head (I cannot quite make it out in the picture).
Post the VIN stamped (stamped, not cast) on the rear block  near the intake and oil pressure sender.

I wonder what Modly is up to. He put a 500 in his '66. I'm sure he put details up somewhere.
At least search here for his old posts. Also look on CadilacPower.com for his posts (same username).

EZ, did you decide to keep the 429 or are you putting the 500 in?

[Speach]

I bought this car without the motor. I would surely be rebuilding a 429 if I had one. Its a sad story the guy who I got the car from lost interest in the car and wanted room in his garage so I bought it. When he bought it, he drove a good distance to pick it up. After arriving to a storage facility the owner popped the hood and the motor was missing. Someone had stolen the motor. Its a good looking car, lower rear fenders are shot and trunk extensions over the body mounts are rusted through. Interior is awesome, and I only payed 1,100 for the car. So now I am back to square one with it and will be working on my 68 until I figure this out or find money and find a 429 for it.

[Speach]

 I will post the numbers up soon. I read the older posts about the swap. I am going to contact him personally about some of the details and start a new thread about it, to clarify some of the details. It appears he just needed to move the motor mounts forward. Of coarse their are some other small things that he had to do, but no cutting or welding. I really would like to put  a 429 in, but finding one and cheap seems close to impossible. I would love to trade one of my 472's for one.  I like the older engines look and would love to keep it original. The original trans came in the car, and the 472 came with a trans as well. I am going to learn about the ins and out of this swap before I make a decision. One option is go nasty with the 472, other option sit and wait for a 429 at the right price. Both options seem good to me at this point.

Ok the numbers for this motor are;

Block cast: 148200
Vin stamp on block: 0524866
Head cast: 1480260                

So my figuring it is a 70-74 472. It does not have any smog stuff, and has an interesting vacuum set up below the dist. I am hoping this is a 70 of coarse. From what I read the 70 was the only 472 to not have the smog set up. I am not sure if this is accurate though. Any and all help is very much appreciated.
