Somebody from TN is building a big cube engine

I've got a pair of guys coming out to pick up an engine that I found. 4.625 bore X 6" stroke factory cast heads. A real stump puller. Not totally sure of the final intent for this deal; but word is they are also picking through the rest of this guys used parts and there are a couple of 800" complete engines to be had reasonably.

What part of TN ?

Not sure where? Kind of a blind call that I got looking for some other stuff.

The guy coming out to get these engines is on the board regularly.

Must be someone with deep pockets !

The guy that has these engines just wants them out of his way. Pretty reasonable price. Just not something everyone can use.

How's the hunting up there in December? I only know of a couple of good engine builders from Tennessee on here..........

We usually have some decent pheasant/quail hunting all winter.

I forgot to mention that these are based on stock blocks.

can you shove a sleve in a stock block and actually get a 4.625 bore? Im thinking there aint much cylinder material there if its a "stock" block. Now mayne an A460 and stock deck height... 800 cu in, that would be a no rod wonder for sure.

Whooohoo just think a 800+ cubic inch Cheater Stock motor.

Actually the guy said if the bores were bad that they could be opened up a little more. These deals are definately not fast RPM deals for sure. Kind of a specialized pulling deal.

800 cu in In a stock block ? ! And was these guy's truck or tractor pullers ?

800" in a 10.3 stock block ain't happening.....

KILL JOY................

I read somewhere that there were guys years ago taking stock blocks and adding up to 2 inch thick deckplates and long sleeves in factory block to get very large cubic inch engines. This would be based on a stock block although highly modified and extremely expensive.

Dave, why do you have to be a buzz kill?

Now we're getting somewhere......

That was before you could go out and buy a tall deck eliminator or aluminum block. For the cost, your further ahead getting the better block as cast.

You could go all out and machine water jacket into the spacers and circulate water (it would look like a modern LSx engine from Chevy) Could also provision the 2" deck plate to covert 10 bolt blocks to 18 head bolts, and use the modern heads.Your talking some time to do 2" steel on CNC, and aluminum would be a whole other ball of headache.


What are the aluminum tall decks 13.5"? Ats a lot of room for cylinder.

12" deck....... Most of the bigger stuff is on a wider bore spacing too.
