What i dont understand is why i would get reversion from my gill set up here is a pic of my tails and the water dumps out about 3" back from the end where it goes out the transom.

Blown engines are different. Not as prone to reversion.

Bob is one of the country's BEST "go to" cam experts you will find...especially for marine offshore hi-perf applications.
Don't wast your time with all the reserch. Tell Bob what you are looking for and he will get you the right cam.

Good idea not to be aggresive with the cam if in doubt. Were does the water blend with the exhaust? I have the EMI's with long risers and the water blend a few inches from the end. I have no experence with the Gills but those look similar to what I use.

Water enters into the pipe 3" from the end of pipe. cant belive it woul pull water all the way back up that pipe for a reversion problem.

I really don't think you will have any issues with the Gil's. They are not anymore prone to reversion than any other wet exhaust.

Griff do you know if the problem they had with gills if any was the manifold itself or the riser.

Possibly, but not always ran as a blown motor. But at low rpms, is there a difference between the 2 inductions? Even with stock intake, still had no problems. The pic was more to show the low rise Gils with silent choice.

I fail to see how reversion could be a problem on the high rise Gils.
