Given that basically an oversize washer has been sold as a reversion dam then I’d think a turbo would be even more effective. I have zero empirical data or experience though. I did find this article interesting on the broad issue of reversion.

thabks that was an interesting article. After reading it I would think a turbo would break up the sound wave pulse and all but eliminate reversion

I dont think turbo engines have reversion issues, like mentioned before the turbine is spinnig just after the engine starts. Now I have seen a video of a water injection nozzel on the inlet of a turbo and you can really see the reversion when the throttle is lifted. Also when I got my turbo cams from Comp, if I remember correctly, the exhaust side has more duration than the exhaust. And with a turbo, wider lobe centerlines are better.

Imo you shouldn't get reversion because you will almost always have back pressure in the headers.

Turbo engines don't need a lot of cam to make power, especially in a mild boat build. Keep the valve overlap at zero and it should live a long healthy life. Cam ground on a 114sep should be fine, depending on duration. Just an example, my last engine had 238/238 @.050 duration on a 114sep. My new cam is 238/242 on a 115 sep. Your not building n/a engines. Turbos are a different animal. Those 2 cams would make peak hp at 7000 and 7200/7300 with my healthy combo. You don't want to spin a boat engine that high.

Guys have made 1000hp on a sbf using 226/226 .512/.512 lift hydro roller cam. Let the turbos do the work.

LS engines have been beat to death. Guys can tell you what will break like clock work at what rpm and boost lol.

I suggest you go over to theturboforums.com and read up. A lot of good info.
