What 44 said, the dual bolt pattern with cool collar are the ones to get, or GenX direct replacement for the 525,600,700, funny how people bash them that have never owned them,

for a stock 496 total waste of money. especially for a heavy cruiser boat with inboards and if it has a muffler box. ??. Your prop options are not that good for any performance gains anyways.

Thanks guys. I have no Idea about the reliability and thank you for the input.. It wouldn't be going thru hull either. Just a replacement for stock. Yes it's a 340 cruiser with V-Drives. I'm sure I won't go the header route with this boat the more I research, I was just seeing if anyone ever used the CMI. Within a couple years I'm hoping to be in a gofast like you guys.

I agree the E-tops are not much more performance then a better design manifold. The KE you are talking about if you see a cut out are basically long tube headers.
But if he just has a 496HO I doubt he would notice and for that matter I have dyno sheets that show the KE lose some mid range on a small motor.
If if I had a staggard boat and needed to buy I would buy the KE’s and paint to match.
That's why I want you to paint my KE's I have in garage!
Thanks,
MD
