Post subject:  Aluminum Slant 6 block
I was at Mopars In The Park in Sacramento yesterday, and one of my friends bought an all aluminum slant 6 engine block.

How rare are these and what are they worth?

It really depends on the condition of the tops of the cylinders. If the aluminum at the tops of the bores is eaten up the block isn't worth much. Of course there could be other faults that make it worthless, but corrosion at the tops of the cylinders is the most common problem. If you or your friend can post pictures of the tops of the cylinders Doug Dutra or one of the other aluminum block aficionados can give their expert opinion.

About 50,000 of these were made between late '61 and early '63. Worth depends heavily on condition: Amount and location of corrosion, whether it includes the necessary separate cast iron upper and lower main bearing caps and rear main seal retainers, cylinder condition and overbore. What'd they pay for it? What are the numbers stamped into the deck surface just outboard of the frontmost cylinder?

It also needs to have all the inserts for the main bearings and caps. :D

Out of the million plus /6's only about 60,000 aluminum blocks were sold, so it's very rare.

It's worth a fortune because it prevents those of us who own one from spending big bucks hopping them up. Only the Doctor has the where-with-all to pull it off.

In reality, it's a good conversation piece and makes a no-power-steering car do-able. Cylinder head sealing, un-replaceable steel cylinder liners, and maybe the fact that it has no re-placeable cam bearings might be the culprit in HP applications and longevity.

I've got almost 5000 miles on my home rebuild and put my foot through the Carter BBS often. Go for it and just make sure you re-torque the head bolts after a rebuild and a few miles.

Don't know the numbers, but he wants to sell it for the right price if anyone's interested.

OK, how about an instant 10% profit. $44!

In 1960 they had plans to install 5000 aluminum blocks in cars. Out of the 5000 1/2 were going to be low blocks and 1/2 were going to be tall blocks, but they produced quite a few less than the 5000 projected. In 1961 they produced 10,767 in production vehicles. In 1962 they produced 36,000. Interestingly enough, in 1958 they produced less than 100 experimental blocks 1/2 were low blocks and 1/2 were tall blocks. As of this date only 1 of these blocks are known to exisist. If you found another one, you have a very rare piece.

Welcome on the board, Aluminum 6 Guy. What is your source for the above, please? Some of it doesn't match my understanding of the chronology, so if I'm wrong I'd like to read up in more detail and correct myself.

Also, which blocks are you referring to, specifically, when you say only 1 is known to exist?

(Keep in mind some aluminum RGs were made early in the 1963 model year, too)

The block I refer to when I say only 1, is the 1958 experimental block.

Ah, the experimental '58 block. Where is it now?

And...where'd the rest of the info you posted come from?
