This is an OEM stock roller cam out of a 89 LX 5.0/302 in 100% working order. in very good shape. Miles on it about 56,000. For stock they work very well with mild blower and turbo cars and trucks. Will work in any 302 or 351 blocks. But older then 85 blocks will need tie bar lift kit to work with a roller cam. Email me questions. Thanks and happy bidding
