I know lb7 acc bracket on the passenger side has the built in pvc drain and lbz doesnt i asume lly doesnt either and the lb7 and lly timing covers i believe are the except the nipple for the pvc drain to drain back into the engine lbz uses a differant size w/p and the bolt spread for the fan pully is slightly differant i was tring a lbz 1 on my motor because it was newer and had lowr miles but wouldnt bolt up
