Can help
I’m refreshing a 1995 502 efi mag
it needs a cam as it was starting to eat a lobe
im up grading the flat tappet for a hydraulic roller
and may go roller rockers as well
without getting the factory Merc eci re programmed I would like a cam recommendation
boat has the factory captains call exhaust and manifolds
don’t want to change the exhaust either
any help or suggestions appreciated

I'm pulling mine next month to install a more aggressive cam so I could supply:
Cam - roller stock 200 hrs, springs from same, Rockers Comp Extreme new (less than an hour),
Let me know if any of this works for you.

I’m interested in the rockers and cam
i need to talk to my builder, I’m out of town for the next week and a half and won’t see him until late next week
what valve cover did you use with the rockers?
and how much for the cam
