SC397 I found a list of cylinder head casting numbers you wrote on a post years back...engine section.But none of them matches my 3231475-2... It uses the modern bridge and stamped rockers.

Thats newer stuff. Check you block. It will have two freeze plugs in the back, next to the flywheel. Newer 360s had those extra plugs

Spud there are no freeze plugs in the back of the block. I removed a rod cap and a main cap looking for dates on the bearings.No luck. They are Federal Mogul made in Italy,to my surprise,std size but no date.

Keep looking. There will be a date of the year embossed on the cylinder head just like the part number. When I get a chance, I will look for more info.

The 3231475 cylinder head was used on 360's from 1972 to 1978. Those have a 58cc combustion chamber. IMG_2614 by Rick Jones, on Flickr

Alright! 72 to 78 is believable by what I heard from the old man who sold it to me. I bet it was a Wagoneer.
The numbers 3 20 are on the cylinder heads. Thank you for helping.

I found the casting date! Its ยด78. I also found 8 sleeves...doomed.
At some point someone sleeved the poor engine and reused the same pistons.
It must be a lower compression ratio engine...

Are you sure that the block has 8 sleeves in it? 360 blocks are easy to find and are cheap. It doesn't make since that someone would put 8 sleeves in it. Maybe you are seeing a witness mark where the gasket was? Even if it did have 8 sleeves, you are not doomed. 360 blocks are thick and there is nothing wrong with sleeves if they are installed correctly. The '78 cylinder head would have a 60-63 cc combustion chamber and the engine would have about 8.5:1 compression ratio. Not a issue because you can bump the compression ratio with off the shelf pistons.

You can also overbore a sleeve. And if it aint broke dont fix it. And another thing you can make plenty of power on 87 octane and 8.7 to 1 compression. And another thing nobody cares how much power it might make when it only takes 50 or 60 to roll down the hiway.

Well AMC blocks are impossible to find down here.Remember what I explained before...AMC never built cars down here. Dodge did with 318s back in the 70s. Ford also built 292s. Chevy never built V8s here...only straight 6s. But yes I am sure its sleeved because I looked from underneath. Wish me luck.
