if your installing a new cam i suggest upgrading your valve springs also. the stock ones wern't great new and yours are 35 years old, plus there only good for about .500 lift. you will also want to upgrade the timing set while your there since the M block engines were retarded from factory. a straight up set will help alot. as for which cam i've read alot of people running comp cam high energy and xtreme energy lines check summit's website.
