I have an Ultradyne H1828 294 R22/22 R8 – can you tell me the type and specs? Hoping I can use it in the 440 that I am building. Thanks!

Though I do appreciate the offer there sir I am really looking for the ultradyne 640 cam so if anyone on here has one preferably brand-new unused or even if someone has the herb McCandless 324 650 lift cam I’d be interested in that too please contact me thanks and have a great day

Thanks I have found what I needed by degreeing the cam shaft. I spoke to another person at Bullet that confirmed this cam is s Roller and that the H7080 is the serial number.

Thanks.

Gary, maybe you can check for the presence of lobe-taper?
If present, then it’s not a roller cam.

Mark West,
I still have a new unused UD cam;
NF57 – Ultradyne mechanical, 255 @ .050″ w/ .582″ valvelift
I’ve had it installed in an engine once, only to remove it for a smaller cam before startup.
Not sure if I want to get rid of it because it was an expensive cam for me to get over here (Europe).
