Long stroke stock sleeve pics
Long stroke stock sleeve pics I got my shortblock back and wanted to take a pic of how much of the piston is out of the hole at BDC. This is a 4.125" stroke Callies crank in a LS2 block.
I remember someone wanting to know how much the piston was out.
Now, I know I will get some ppl that will say that was stupid or that it will burn oil or something like that. I knew it wasn't the most popular option for a stroker. Is it an ideal setup, no. Is it for big power adders, no. Do you want any old machine shop to build you one, no. It should be good for my use tho, a good street motor with good low end.

Got the same setup on my LS1, callies 383 stroker with compstar rods, had no problems with it except I had to chop most of the windage tray and space it out since I had to use a modified oil pan.
Here's a pic of my #8 piston at the bottom of it's stroke
And here's the Rod bolt hitting the block, before the block was clearanced:

Have fun with that bad boy of yours!

I'll post a picture later of my Wiseco pistons and how the skirt was damaged because of this same thing. Although I was on a 4.0" stroke.
IMO for long stroke engines the bore tolerances need to be tight, and the pistons needs a well designed skirt.
I'm going for a shorter stroke crank now.

Actually, the biggest issue with the longer stroke on stock sleeves is the piston taper. If the piston comes out of the hole too much at BDC, without the proper piston taper, the piston will rock too much, beating up the skirts. This is why custom pistons are generally better than off the shelf pistons made for a specific stroke. Longevity is the issue without longer (darton LS7) sleeves if using shelf pistons.
