Here are some pics of the sleeve machining and installation process.




first thing is the block setup in the cnc-here the probe is finding the crankshaft center line




now we find the camshaft centerline-this way we ensure the bores and decks are exactly 45 deg from the camshaft to crankshaft centerline




now we probe the bore locations to determine the location of the bores




now we probe the decks in 6 locations on each bank-this tells us the height and straightness of the decks




here is a report of the locations of the bores and the deck heights-the x locations in parenthesis are the blueprint locations the one beside them are actual.All y locations should be zero




here we are rough boring-this will get us to within .020 of the actual size




block after rough boring




couple shavings underneath




finish boring-we need to be within .0002 when finish boring-that's 2 ten thousanth's of an inch.Accuracy is really the key here-if not bored perfectly-you can crack the block when installing the sleeve or you can have a loose sleeve.There are not too many machines out there that can hold this accuracy-we are very fortunate to have one.




bores ready for sleeves




sleeves installed




ready for final machining

Great pics and writeup of the sleeve install. Very confidence inspiring.

I'd assume this is much stronger than a ls7 sleeve right? How long are the sleeves? Is there any room for a rebuild later down the road?

The attention to detail is very impressive

Yes, they are much stronger and harder than stock. They will wear much better and deform much less.

Subscribing; this is some cool chit.

I'm going to see if we can get Shawn to strap a web cam to his forehead so we can watch it all...

Very cool! Thanks for taking time to document the process and provide an explanation for each step.

here is the block decked to the proper height-give or take .0001

hopefully next week i can get the block honed and rotating asy balanced-i got a lot of other blocks to hone as well

Looks great, have fun deburring that

Damn looks good. Can it be opened up more for future rebuilds? I wish something like this was reliable for ls1/6 blocks, but everything seems to have a downside.

You could always do a wet sleeve for an LS1 block...

Hey... lemme bring my car over and you can put that in mine Kevin will never know the difference!

I've seen the Darton ones, but always hear more negative comments than positive. Something about haveing a hard time sealing them up or mixing water and oil, etc.

Shawn @ VA Speed

not only that the cost is prohibitive-you can have a sleeved ls2 for less and have a better piece in the end

This is just too sweet.

I think someone else asked, are you able to rebuild this resleeved block down the road?

Shawn @ VA Speed

iTrader: (3)

these can be taken to a 4.155 bore-so if you start at 4.125,you can rebuild several times-this block could last for several seasons even in a race application that gets honed .005 over every season.

How much is to much as far as stroke goes. Can you run a 4.100"-4.125" crank with minimal clearancing? I wish all this stuff was around when I built my 383. I'd assume you can do the same type of sleeve to a l92/ls3 and ls7 block correct?
