Recently had my almost new cam and lifters fail in my l82 motor...given the engine is old and unknown kms I’ve decided to order a crate sp/zz partial engine however I had just redone my whole top end (dart shp heads,dome etc etc) wondering if anyone can tell me what from the original motor will transfer to the new zz.ive spent countless hours searching online and can’t even really find a year range for the zz engines any help is appreciated!!!
