Yay, here's mine for the hell of it. We should start a picture thread of cracked sleeves.
I can tell you though, that little bit of dinging on your head can be cleaned up. But that's totally up to you. Remember though, increasing the CC's of the combustion chamber will drop compression.

Get the 2.2L forged rods from Eagle for $300
http://www.cimotorsports.net/motor-s...ec-cobalt.html
and the 2.2L forged pistons from Diamond or Wiseco for $400-$500
You will have a kick ass set of rods a lot cheaper then whats out there right now. Not to mention the added benifit the longer rod, like:
like less stress on the cylnder walls due to the piston will travel straighter in the bore
less stress on the piston skirt lbecause it will travel straighter in the bore
less stress on the cranck because you decrease rod angle
you slow the piston speed down
it will also give the engine the ability to rev faster and higher due to all the above

^^ 2.2L & 2.0L rods are exactly the same in length, the only difference is the wrist pin diameter, 2.0 LSJ wrist pin is much larger than the 2.2 L61. Pistons are different. 2.0 cylinders have a 96mm bore and 9.5:1 compression stock... and the 2.2 have a 86mm bore with a 10:1 compression stock.
I personally would stick with the stouter wrist pins and go forged on the 2.0 components versus custom "2.2l" style pistons if you wanted to go that route. They are not directly interchangeable.
That... and if you were actually changing rod length, that would effect the compression ratio in cylinder as well as the measured stroke... The LSJ has a dead even bore/stroke ratio which is GREAT for higher revving applications. LSJ = win.

2.2 = 5.765 is the length pin diameter is 20 mm
2.0 = 5.728 is the length pin diameter is 23 mm
I don't think the pin diameter would make that big of a difference. Plus the 20mm eagle pin is most likely stronger then the 23mm stock LSJ pin. And they use a different pin location.
But you can change the rod length or the piston compression height to accommodate the longer stroke
I am not trying to say that using forged internals designed for the 2.2 is 100x better then using Stock LSJ parts. I am just giving an alternative to $900 forged LSJ rods to have a fully forged engine.
There is a guy on RLFs working through trying to figure out how to make this work on the LSJ. If anything, I find it interesting to "think outside the box" a little see if there is anyway to improve on something that is already pretty good.

I was under the impression the rods were the same length, my mistake. I've even looked at them next to eachother when my LSJ rods were out.. I suppose the difference is too minimal to be real noticeable without using verniers, but the wrist pin diameter difference was blatently obvious, I was looking more at that anyways.

Well time for an update and more pictures of the progress. Today's goal was to get the rest of the motor out of the car and with some time that was accomplished.
First up they got the bumper off the car, removed the remaining piping, and other misc connections.
Parts randomly gathered behind his car
The 3 day old ported head
Slowswap pulling out what was left of the motor
Contemplation of what truly happened
Oh Hi I has cracks in me
Rock on Slowswap, rock on
And Finally how the car is currently sitting until a new block arrives for assembly

yeah send him the rotating assy minus pistons. diamond are made to order. some vendors have em on the shelf i had to wait 2 weeks so you might wanna get that rolling.
Ray can get you the bearings for cheap. that block is possibly good, he removes all that material anyways when drilling the block for the sleeves. he saved mine but mine was not that bad lol
but for the shipping freight and the price he sells em for i would just buy one of his.

one more question, so were gonna have to install the pistons ourselves correct? he doesnt do that? and what is your opinion on getting the coatings on the pistons? waste of money or is it worth it?

he will also prolly tell you to use one of those rubbermaid large plastic bins to ship them in.
just put it in there, and use a strap and bolt it shut. still havnt figured out the details, but along those lines lol, im only going off what he gave me. but if he has blocks for the cheap, it might be cheaper to buy one of this.
let me know if you get any info, as i will do the same.

ray can assemeble and do almost anything on these engines. he really knows these engines. im getting ready to send my shortblock out, along with pistons, rings, NBS and he is going to install sleeves, and assemeble everything on the bottom end. he has all the bearings and bolts there, i didnt have to purchase them.

and we need 10 or 12 cant rememberbut he'll tell you to get them cause he has to trq the main girdle in order to check the clearences and the stock bolts are half the price but they are trq to yield and you would have to but 2 sets so he will advise you to just go with the studs.

Great thanks man I appreciate it. It looks like my engine builder and I aren't exactly going to work for certain reasons so I need to move on and look elsewhere. I am thinking about ottp since they are close, but.... I don't know.
