Yes, it's used, we had it in an A15 for a couple of supersprints, then realised we needed a bigger cam. The A15 was 1598 cc with big ports, etc, so the cam just wasn't good enough, compared to another fellow with a duplicate motor with an arthur johnson cam. I've looked in the shed & it has 4d655 stamped on the back. I tried googling this number, but got nothing back. It's not a wade part number, it's not camtech, or tighe engineering. It's got all the journals & lobes taped up to protect them, plus it is definitely a late type cam. Unfortuneately the fellow I got it through retired 5 years ago, but I might be able to track him down tomorrow, to see if he can remember who he got the cam off. It's definitely got a lot off the back of the lobe, compared to the standard cam that was in the same box.

PS when I got Camtech to regrind some lifters for me, they gave me grief because they weren't clean. Seeing as they were oiled up to protect them from corrosion, I was quite active in my reply. This brought the cam grinder himself to the front, where he agreed with me. bit of a shock for the counter jumper, really.
