I just found an aluminum slant 6 block. it is a block only with no head or crank will the head and crank interchange from other engines????

First, give the block a very careful examination. Look for corrosion at the rear of the block, both inside and outside the water jacket. Measure the bore diameter closely. There's not much room for an overbore, and even then, it's a small overbore. Does the block have the "saddles" with it? The crank and main bearings set into a "saddle" that inserts into the block, and is all held together with main bearing caps that use an undercut bolt, threading into the block.
Head gaskets are getting scarce, and I'm nor sure there's a decent alternative for the ally block.
You can use components from an iron 225, but the standard line-hone practice will apply when swapping cranks. The ally slant had heads marked "special", but that applied due to Mopar carefully selecting heads that the combustion chamber(s) more closely lined up with the bore, instead of the "regular" iron production engines.

Good luck.....Roger

Er-ruh…no, they don't. The aluminum block uses iron upper and lower main bearing caps, four of each, but there's no one-piece saddle of any kind.

Only the earliest '61-built aluminum 225s had heads marked "Special".

(Think you mean "alloy")

...plus extra clearance for the pushrods. Tighter combustion chamber placement and extra pushrod clearance were built into all Slant-6 heads officially starting in '63 and actually starting mid-'62.

You say upper and lower main caps, and I said "saddles", (meaning the uppers). Thus the reasoning for my quotation marks on the words "saddles". Just a difference in terminology.

No, I don't mean "alloy". I mean "ally", as in an abbreviation for aluminum. Good clarification, though, as I wasn't privy to that little tidbit of info. (Although I should have said "had iron heads")

Again, a good clarification. I knew more knowledgable folks would come along with info he could really use. Let's just hope he has found a good, usable block. If nothing else, he can use it as a conversation piece and "setup" block like I use mine.

That is correct. Good deal any way you look at it.

It's not in your garage, yet?
As Rick said...A good deal any way you slice it.

If the block is junk, buff it up and make a coffee table for the man cave.

BTW; Would you care to share your general location?

Glad to see Steve is still in the Slanted game. I caught up with him at Carlisle 2015 for 10-15 min, which was fun.
