No the foam goes in the intake snorkle.
Problem I see is once you get the foam the correct size you are done. No need to adjust anymore.
Wow, you guys have been busy! Some cool stuff there. I use foam with my kit because it keeps the cost and work to a minimum, and it works as well as any high-zoot restrictions. In fact the name "2 minute mod jet kit " was developed here on this forum several years ago, because we could change the jetting "in 2 minutes". We discussed making adjustable restrictors, and actually Jim Snyder is the first to have done so. Upon reviewing costs, etc on various threads, it seemed that the average connie owner - being a "frugal" guy - would be as happy with foam, as long as it was easy to install and it worked.
What I find most interesting is that when I first introduced the idea of restricting the intake for power, it met with a LOT of questions. Common hotrodding dogma has always been to open the intake, I was advocating to restrict it. Heck, there's even a factory sticker on the intake that says "do not let anything obstruct this airbox intake". Now Here we are some years later, and restricting the intake is just "the accepted way to do things". Funny how that works... Steve
I really like your design Joe and am trying to figure it out. Do the cams restict the openings by themselves or do the push the snorkle pieces together? Or am I totally wrong?

Steve, I had all the stuff I needed to create my version just laying around asking to be used up. (except the round wood stock, cost me around $3.00)
I think last time I had spoke to you we discussed me changing all the jetting from the 36mm carbs over to the 32's so I knew there was going to be allot more tuning and then dyno runs. I already had the 36's out to change the fuel rail "O" rings so getting the airbox out to play with it was no problem. Also had plenty of time to experiment during the long cold winter.

Wayne, the cams push the top of the snorkels down to close up the openings on both sides evenly.Thanks Joe, I am too lazy to do it but the next time those carbs are out! Maybe. Well thought out sir.
The first picture shows me closing one side down by hand to show what it looks like in use, the second picture shows how I cut
the top edge on the 90* side and cut toward the middle of the curved side.
Well, since it came back to life, I have a question that I just haven't had the time to diagose. I have the "power" kit from Steve with pretty much 40% foam blocking (almost one complete snorkle opening). No engine mods other than the 4 degree advance plate that has been in this thing for years, a K&N filter (properly oiled as far as I can tell), and T-Cro's coils. When cold, it starts up great with a hit of the choke, I give it a few seconds to smooth out, and away I go. Runs like a top in all RPM ranges. If it is an exceptionally hot day, it will sometimes stumble at a traffic light and will sometimes want to cut off if I don't add a few RPMs. It it does cut off under this condition, it needs a little bit of cranking with absolutely NO throttle.
So, does is this mean I need to ADD a little bit more of the blocking foam? Is it better or any difference to split the blocking to each snorkle opening? For those running foam blocks, how much are you using (as a percent)?
