324 build for a 66 CS?

The motor in question has #10heads. Don’t know if it is actually a 324. It was installed on a work boat and taken out for winterization. The boat was sold and now I can acquire the motor for cheap. Will this motor bolt up on my 4Door 66 for future use? My 330 is going to stay with the vehicle for now, as it starts up and no smoke, but while I toy with the thoughts of building my own rocket, I would appreciate any thoughts on this project.

The last year the 324 was built was 1956. There is no way this engine will fit in your 66 or could be made to fit.

Would still be fun to build. A good learning experience

Look for a 350, I had a hard time selling a good running 350, finally got $200 for it.

Its your money, there are better boat anchors to use for a start of an engine build that will yield more fun for less money.

The motor mounts on a 324 are in a completely different place than in your car. Use the 324 in a 50's-60's Olds, less headaches and fabrication.
.....Just my two cents worth.

I agree with the above, to much grief and cost for no advantage, When you get done you will have a 240 hp engine that is strange to everyone with a 65 year old transmission that few will know how to repair, just doesn't pencil out. It would be different though, but even I who loves 324's would look and shake my head.... Just saying...... Tedd

now a good running 350 within a couple hundred miles of me sparks an interest for around the same price

You can get a 350 or 455 core for around that price.

The sellers original post stated “455?” I observed his photos and saw the #10 on his heads, and used this forum to look the numbers up. I was just curious to see what he actually had. I figured I could get some input from you guys.

What happened to the idea of keeping the car all original?

nothing happened to that, I was just scrolling through some seller adds and saw what I thought might be a good deal on a motor to build and maybe keep for a future project. The seller didn’t know what was in the said vehicle, and I used the forum to find some information. I was just curious on weather the block would fit in what I have or not. I have yet to get what I have road worthy, as I still have to do break work, and a few other things. I am just learning a lot stuff right now, and with this thread I chalk up another learning lesson. Thanks

It was common for boats in the 1970's to have Olds 455's. Where did you see the #10 on the head? The 324 and 455 look very different, you should be able to find photos of a 455 and compare that with his for sale ad.

Since you are unsure of what it actually is, post a photo of the engine and you may get a little more info as to whether it is a 324 or not...

i have yet to receive the extra photos photos the seller was going to take. But I did try to find a photo of a 324 sitting out maybe on a motor stand or something... I sent him quotes from different forums showing where the casting numbers are on the motor for the older block. I am sure I may be wrong. The number looked similar to a 10 on the shelf of the head, rear of the motor. On the left side, near the oil filter. Big block style number maybe about a inch tall.

It still has the fresh water keel cooling system on it and a velvet drive transmission.

Post pics of the engine in question that you have. The valve covers are much different, the valve gear is very different. Too much guessing going on.

OK, not a 324. I'm not sure what it is, maybe a 260 or a 307? Someone familiar with late 1970's or 1980's engines will have to chime in.

If you can get a picture of the valve covers and it has more than 2 bolts holding them on per side it's not a 324. I may have a interest in it if it does turn out to be a 324 and is in the left side of the states. Those are very heavy engines, freight would be a killer.... Tedd

Whatever it is it is a marine engine. Look at the exhaust manifolds. That said and the fact it is blue, it might be a 455.

What did you use to look up the numbers ? A photo posted earlier would have cleared up the "324" error much earlier.

I am sure you created more confusion than providing information. What kind of quotes did you send him ?

I suspect that by now, he doesn't consider you serious or knowledgeable. You may never hear from him again.
......Just my two cents worth.

Actualy I have received more photos, and I didn’t tell him what he had. I sent him a copy and paste from an engine identification chart, found in google search. I think it is wrong to assume someone who is ignorant of a few facts, and tryin to find out a few things in a forum, has just became an overnight expert. So yesterday I didn’t get a response because I was letting him do a little work himself, instead of doing all the work here and there myself. Obviously I am hard at work trying to discover more info in the hobby of classic car building, and I do appreciate the help you guys have applied. I do think respect is a two way street.

You may have already found this, but I just came up with a reference showing the 1976-77 260 engine used a #10 head. I believe that's the engine your looking at. There's always a chance the heads were swapped onto another small block. But this does look like a small block rather than big block Olds engine. John

Look at the casting number on the block to the right of the oil fill tube, that should answer the question more accurately...

i wait for these photos... The seller sent more photos last night and the only photo that contained any numbers wasn’t a very good shot and it only had 3 numbers. Was on the side of the head at the exhaust port 3 digits. I think there are 3 more numbers on the other side of the port, but he didn’t focus on that number.

I have to confess, that photo was taken from the internet, and is not the 400 engine in my 66...
