370 LQ9 shortblock This was the engine that I had originally planned to put in my car. As you can see in the pics, a piece of the block broke. I ended up putting a different engine in and now want to sell this one.
I paid $1,000 in labor alone and it has over $1,000 in parts not including the block or crank. I took the block to Easterwood Performance in Raytown, Missouri to have it looked at. Dick Easterwood (816-353-6869) said the block can be fixed and he would do it for $200. I mention this to give you an idea of cost to fix. The engine has to be disassembled down to the bare block to get welded, then you have to reassemble it. It should be easy for anyone wanting to spend the time to do it. All the bearings are correct for it so as long as you keep it in the correct order, it's damn near fool proof. I simply do not have the time to deal with this.
Here is the rundown
LQ9 6.0 blocked bored .030 by Burlington Performance
Diamond pistons 2cc valve relief’s, valve depth intake .165" exhaust .107" Flat tops
Eagle Rods part number CRS6125B3d
New rings, bearings, plugs
Stock cranked cleaned up (not sure if it was turned)
Bore and Stroke: 4.030 / 3.622 to achieve 370 ci
this motor has ZERO miles and never even made it into my car
$1,100 + shipping
Pics assembled before it broke and after broken. I have plenty more I can email.

I don't really know how to calculate compression, but I imagine it can stay close to stock with the right headgasket. -2cc valve relief isn't much

A stock head is a 66.67 cc head if your talking about a LS1 casting.
The stock casting for a 6.0 block is 72cc's.
It also depends on gasket used and deck height.
See my link below.
You will be between 10.5:1-11.0 CR with a stock LS1 head depending on deck height and gasket.
A .040 gasket should achieve 11:1.
Now using a 72 cc 6.0 or LQ9 head you can get compression down to 10:1
