yeah i found some new comp cams for a reasonable price. one seems like a good cam with .490 lift on both intake and exhaust. got my new pistons and rings in the mail today and both were packaged wrong! i need .060 pistons. they sent .040 pistons in a .060 box. the rings they sent are in a .060 box and wont even fit the .040 pistons. i think they might be standards.

See if you can get any more information on the cams your looking at.

.490 lift range is in the stock replacment, smooth idle catagory. The factory performance cams start around .500-.515 lift. Street/strip cams are around .535-.560 lift.

The other specifications (duration, lobe seperation) will help identify how the cam will work.
