93 merc 600 sc

Before i take the cams out i bought 2 502 600 sc's with 60 hours on them but i didn't hear them run..i decided to freshen them up and was wondering if thease cams are radical,if they had a decent idle or real lopy..does somebody have a video of their 600 sc's idling and can direct me to the vid?

1993 600sc with B&M superchargers with twin carb's..

thanx in advance

They aren't very radical at all. For some reason, I am thinking they are flat tappets. I may be wrong, but I think they are.

Mike,
They are a Crane flat tappet.
300°/300° @ .004”
240°/240° @.050”
.329”/.329” Lobe
.559”/.559’ Valve
110° LSA
105° ICL (+5°)
While not necessarily radical, this is actually very typical of 20 year old camshaft design.
