I am building a new 572 , dart block , scat crank and all the rest .
Does any one know of a good cam ? My builder is suggesting the merc 525 cam
I am running dry setup , shell i go bigger than that as cam?

Call bob madera at marine kinetics and be done with it.
Custom ground cams specific to each application with excellent results.

X2. Thread over

Merc 525 cam is to mild for a 572.

As suggested call Bob M.

The cam is 632 lift 244ex/230in

Yes, call Bob. First thing he's going to ask you is what heads.

The 525 cam will be like a tow truck cam in a 572.

If that's the builders suggestion I'd find another builder.

Lol, I don't know if I'd go that far.

Agreed, call Bob M.

Make sure you've got about 30-45 min to talk, its gonna take some time!
