These Swiftune cams have a rep for wearing out fast, they are too pointy on the lobe. More so if you run 1.5 rockers with them.
I had the same problem with a Camtech 619 (VP3) with 1.5s, it did take 45,000 miles to cark it.
I now run GR's cams, an RE13 in the 1412 stroker and RE282 (sprint cam) in the 1360. Both with 1.5 rockers. They have a nice big nose radius. After 11,000 miles the 282 cam still has full lift on all lobes.
