Does anyone know what they are. They sound much different than the 500 EFI's, better.

Lunati makes a cam part number 02005. It's lunatis version of cranes 525sc cam. It not a roller. I dont have cranes part number off hand but I have got it some where. The specs on lunatis are at ,.050" 224 and 234 with lift of .534 and .559 with a 114 deg sep.

Thanks Scarab but this is the new (EFI) 525.

sorry, my bad. Its possible that its the same cam it just sounds smoother because of the fuel injection. If any has the answer I would like to know also. I'm guessing its crane's 139741 roller cam.

due to the headers and increased compression would be a good guess.

More likely a Crane 16HR00004
298/306 adv, 236/244 @ .050, .610/.632 on a 114 LC

Thats the specs on the crane 168741. Probably just a different part #?Bob

Adivanman

The 168741 is on a 112° LC while the 16HR is on a 114°

Advanman- You could be right....but don't you guys think the upgraded heads and a true scavenging exhaust is worth more than 25hp, all things being equal [HP500 To HP525]?? The cam you guys are speculating is decent jump from an HP500. I would guess same cam and maybe even a little less on the exhaust because of the headers, say a 230/230 114 lsa??? Take Care Berg

i thought we were talking about sound??...NOT power.
