Cam specs HP500 carb motor?

[Ted]

Can anyone tell me or look up the cam specs on an HP500 carb motor please. Just need lift and duration if possible. Is it the same as the EFI HP500?

the carb and efi are not the same.

and for future reference, EFI: http://www.cranecams.com/index.php?s...21&lvl=2&prt=5

That's odd, the Merc Manual lists the EFI cam as .342 lobe lift both intake and exhaust.
