CMI headers for small block
 

Anyone using these? Curious what performance gains one could expect on a stock 6.2L (320HP). CMI claims about 10% but would like to hear real world numbers (dyno or speed).

I also was wondering how they work. Wonder how much more cam they can handle with out water revision? Will they work with captains call?

I just bought a pair of the new E-tops but didn't get them installed yet.
The new E-tops are a direct bolt on that don't require any modifications or additional tails so they should work with your CC.
I'm unsure on the reversion, but just give them a call and ask. I went up there with the boat just to be sure of fitment and they were SUPER nice guys, gave me a tour and I even walked out with a couple free T's

Thanks for the info wowchad. Do the E-tops have provisions to mount the ECM and throttle/shifter brackets? Good luck on the install and post some pics if you can.

Yes they do offer both of those brackets. In fact they forgot mine and the next day the came in.
I can take pics but I don't think I can post them on here b/c I don't pay for my membership. I'll see what I can do, maybe I can post them on hotboatpics and link to them.
Give me a couple mins...

Here are some pics wowchad emailed to me. They sure do look nice! Let us know how they work out regarding fit and performance. Thanks.
