i have a gsr block i want to use ls crank with eagle ls rods and 9.6 cp pistons what do i have to do to make that crank fit i want to keeo my block cuz it got girdle and oil squirters

 

nothing just drop it in. spin the assembly over to check and see where the oil squirters are hitting and bend them so that they won't make contact with the pistons. other than that and making sure you have the right clearances for the bearing, you are set my friend. remember to use LS pistons as well
