You are not going to be able to run any upgraded cam with the stock cast risers. It dumps too close to the exhaust manifold.
The 500efi and 525 cam are both capable of being run with silent choice diverters, just not the factory 502mpi manifold/risers. Also, without some good exhaust, you are not going to see the real gains of any upgrades.

500efi cam, with some good aluminum manifolds, and short stainless risers for the captain's call.
Send your ecu to Crockett.
The engine will make 80-100HP more than stock...

I did not expect such a response. I left a lot out. I have already installed a set of cyclone S.S. Headers, MSD-6M control box distributor and coil, K&N large size flame arrestor. What I have on hand is a set of 308 Dart Iron Eagle heads (2.250 intake, 1.88 exhaust and 119cc combustion chamber) and a set of Comp Cam roller rocker arms, Cloyes timing chain. I plan on swapping out all the parts at one time. The only thing I need is a cam. I am concerned with water inversion.
Any help on choosing a cam would be appreciated.

I'd still say 500efi cam because there are proven programs for the ecu.
The 525efi cam may be on the edge for captain's call. Merc uses large sweeping headers with that cam.

Called CP Performance, they told me that they can reprogram my E.C.M. in the same way as Arizona Speed, Flagship, and Keith Eickert would. All I have to do is fill out their spec sheet. Who do you suggest for reprogramming my E.C.M.?
CP prices for the cam is $290.00 and $517.00 for the lifters. Seems to be a bit high. They are Comp Cam parts.

Tyler Crockett or Mark at Precisionmarine EFI for the ECU.
Talk to the programer before you buy a cam. If your not going to dyno the engine, you want a proven combo.
That is why Griff and I have suggested the Crane/Merc 500EFI cam.
