Sleeving

[austindavis1993]

I was just wondering if it was possible to sleeve a 3.0 and if so the process of doing so?

The SHO Shop did it and it did not go well.

If you can find some one who can do a good job it may be possible to have it done but it will cost a good amount. Boost would be more cost effective.

You can currently go to 3.3 without sleeving.

It should be possible to sleeve the engines.
Generally speaking, you have to source a sleeve in the size range. You then overbore the existing cylinder for a light press fit, but don't bore to the bottom of the original cylinder, leave a little of the original bore to offer a stop. Through heat / cool of the various parts, you press fit the sleeve into the block, till it bottoms out, then you can deck the block to trim the sleeve to length.
Quarter mile people do this regularily, as they usually have a lot of coin in the block they are using.
While you can still buy a running engine for less than a new blower control module, this machine shop activity is considered "over-spending" on these motors to date.
But that will change.

People crush perfectly good 3.0s because nobody wants them......

In my area, a local entheusiest restored a 57 Ford Retractable Hardtop lately. Somehow, it was the model with the 312, equipped with the 2 x 4-barrel carbs, which was unusual, as that combo usually ended up in T-birds. He did not have the correct engine, so he did a continent wide search for one. He paid $10,500 + shipping for a non-running 312 which needed block repairs in the bell-housing area, and a total rebuild.
Over the years, I am sure some of them got crushed as well.
Just a cautionary tale.

I have a machined 3.2 block machined for a set of 3.681 pistons. 8.5:1 compression. sized for 3.0 rods. If you have rods and a crank I have a block and pistons sitting here at my house that are just taking up space.

editL this was for my SHO swapped camaro but I got sent the wrong pistons by mistake. I needed pistons for 3.2 rods, and a smaller bore. It was a bit of a *********** but in the end I am stuck with a block that is cut to these pistons.

The matching pistons for this block are available for sale (they actually belong to us - we provided replacement pistons to Alex N/C).

Here are the specs:

93.5 mm
8.5:1
0.010" in the hole
Our standard oversized and deep valve pockets
Piston offset
21 mm pin
HD for NOS/Blower
XX rings
Armorglide Xylan skirt coating


As above, Alex has a block already bored out for these pistons. You just need to supply a crank and 21 mm (MTX) rods as he notes.

These pistons would cost $830 + $85 for the skirt coating = $915.

I'll waive the cost of the skirt coating to move them. So just the $830, available now.
