My buddy has been running that cam in a pair of N/A 454's for many many years. Competition marine center rebuild his original 370 merc's, and installed those cams. Up until 2 years ago, it had stock center rise cast iron merc manifolds, and never had any reversion issues. Now it has headers and dry tailpipes. i wouldn't have believed it unless I saw it, which I did.

Wayne272 is running those cams, in his 31 Bullet, with 177 superchargers, and GIL manifolds with wet tails if memory serves me right. No reversion issues.

Not true, Degree your cam and make sure does not have more than 2* advance use ICL method, install at 112 ICL. This will promote better breathing & useable top end power.

MT - what ignition modules on the above 2 motors ?

The NA one has standard 24 deg merc modules. I believe the supercharged ones do as well, but im not 100 percent. I know he was talking about getting the V6 modules, which allow alot more initial as we know.

I just want to make sure that it's still stated that I am happy overall with my build from Steve. Everything looks top notch and I am confident everything is done well. I just am not a big fan of the cam swap. I would have him build my next motor. I am going to call him in the morning.

If he has a dyno, why not dyno it ? See if his numbers add up.

Textbook says that cam isnt ideal. Thats textbook. Who knows, it may work better than the other cams. Never know until you try it.

Tell him to shove his cam up his a55.

Or that lol

I called comp cams, they informed me that that cam will revert with wet exhaust. They also said it was not great for a supercharger.
I also called Emi Marine. They said that the comp cam was a bit over what they call safe and would likely revert. I then called the builder. I am waiting on a return call.

This should be interesting.
