Hey FABO, I was wondering if anyone has sleeved a 340 in preparation for a 416 Stroker kit. The machine shop was worried that the sleeve would not clear the 4 inch stroke that crank has. Has anyone sleeved a 340 and had any issues with it? Thanks!
 
I had one sleeved a few months ago for a 418. My builder had to clearance the very bottom of the block itself, not the sleeve.

Sleeves don't protrude into the crankcase. They machine the bore for a sleeve leaving a step the bottom for the sleeve to stop against when it is installed. They bore almost to the bottom. Find yourself a new shop.
 
Brian at IMM sleeved my 340 and built a nice little 416. Shouldn't be a problem finding someone in NE to do it and do it with experience and expertise.
 
I'm lost. What does it need sleeved to be a stroker?
 
You are over-thinking it. It doesn't need to be sleeved to be a stroker. His stroker needs a cylinder to be sleeved because it got fk'ed. :)
Well he didn't say that, so I wasn't going to assume. And that was my point. A sleeve has nothing to do with it being a stroker.
 
Steve does many of them. On some I have seen him heat the block and put the sleeve in dry ice. And then press them in. The other day we were at Steve's friends shop getting material. There were sleeves there for a diesel engine for a military tank. 6" diameter over 1/2" thick about 10" long. The sleeve pictured below being installed in a JD stroker for a pulling tractor was a baby to them. SK machine Danielsville Pa. 18038 do a google search. Call ask for Steve , He will tell you what is involved for what you want to do.

If he heats the block and freezes the sleeve, there ain't much pressin goin on. It probably just about falls in. lol Smart boy.
 
I knew a guy that was as stubborn as anyone you can imagine. He put THREE sleeves in a 340. He was absolutely committed to building a stroked 340.
He did follow through but was repeatedly spanked by me with my stroked 440.

Not every one does it the same . But as long as the end result works without leaks and is positioned correctly you'll be good. If the cylinder is cracked it must be sleeved.

Did you all know that sleeves in aluminum blocks need to be .003 above the deck to allow for block expansion. If not when the engine gets hot the block lifts the head off of the sleeve at the compression ring on the gasket from the aluminum expanding more then the steel.

So the block must be square decked before the sleeves are installed. The the sleeves are milled .003 above the deck

You don’t leave the sleeve proud on a block that take a straight sleeve. Ever.

And I believe you meant protrude not proud.

I am telling you that is what happens . Call the shop and talk to Steve and tell him that is wrong. See what he tells you. I seen him cutting a block before the sleeves were installed. That is what he told me and I don't think he would lie to me

He does them all the time for a speed shop that builds high end cars. No gasket failures since with 60 lbs of boost. 1000 HP 4 cylinders. He does the block and head work for all of them. There was always 10 or more here at one time for the same speed shop. Cope performance. He also does all the Viper engines and heads for Havok performance. Big boost twin turbo cars . They get cars from all over the states. Steve does all the custom engine work

Ok, I’ve set several hundred sleeves, probably closer to 500 and you never leave the sleeve proud unless it’s a sleeve with a hat on it.

The block the OP has doesn’t need a sleeve with the hat.


Edit: here’s the issue Steve. You don’t have a clue when you jump in a thread and talk about leaving the sleeve proud.

The OP does NOT have an aluminum block, nor is he using a a sleeve with the flange (hat) on it.

I get that you are rightly proud of your son but posting **** that is absolutely irrelevant to what the OP is asking just gets **** in people’s head. And then it needs to be corrected.

Just like right now.

So when someone asks about setting sleeves in an aluminum block then you can talk about protrusion.

In this case it’s wrong to even go there.

Boys,boys, two of the most respected guy on here. Y’all shouldn’t be going after one another.
 
Yes a sleeve will work with a 4.00" stroke, but unless it's to restore an original 340 for restoration purposes I wouldn't bother.
Bite the bullet and look for a 5.9 core and settle for a meager 8 less cubes.
