Looking to buy a new cam because the one I have won't work I have a 95 firebird formula and need the cam for vented opti-spark (the one with the bigger center hole and larger dowel pin). Anything around .510/.540 with 230 duration or so. Let me know what you guys have, new or used with low miles. Am willing to trade cams too. Thanks

mine now is in the for sale section
