you can use the mains as they are the same as ls.... but the crank is different on the rod journals they are different..... you cant use gsr rods on a ls crank...... you will need to get ls rod bearings and use either gsr or ls mains... no biggie... acls are like 30bux at your door
GSR and LS Mains are NOT THE SAME im almost positive
EDIT: im right
