2.2 question
I might be changing direction on my Cobalt plans....does anyone have any detailed info on the 2.2 motor like stroke, bore, piston type, rod length, etc. ? I've been doing a little research but haven't really found anything. I'd appreciate any help on this. Thanks

Bore & stroke (in.) 3.4 x 3.7
Bore & stroke (mm) 86.00 x 94.60
Block material cast-aluminum
Cylinder head material cast-aluminum
Thats off the www.chevy.com/cobalt
Dunno if that helped or not. Im not good with this car stuff.
