WCS: I talked to Inline yesterday. They don't have any bare blocks. They do have a completly built bottom end. No milage on it. It would save you the hassle of sending it off or whatever.
Here's what specs from what I can remember:
GSR block...bored to 84.5mm
Darton sleeves
Crower rods
JE Pistons
Crank has been been touched, but don't remember what they did.
Hot tanked
Blueprinted and balanced.
New oil pump, gaskets, seals, rings, etc....
They are asking 3k for it.
I dunno....you probably wanna send it off yourself and get your specs, but its a pretty darn good deal!
