I've always wondered, why not tap into the HVAC cowl vent instead? It would make a nice factory look with all the benifits of a cowl intake. Obviously I am missing something on why people don't do it. Not enough air flow?
I am pretty sure you could do this. There is already a drain for the cowl (obviously) so as long as you could get a 3" tube in there somewhere, should work!
I actually have my heater box out right now, I might take a look at it tonight.

I like the hummer intake. I plan on doing this on mine. I just have to figure out how to make (or what to use as) an air box with filter to connect to my carb without restricting too much air flow to the v8.
WOW I just started my intake mod and I have to say it`s a little more cramped working in that area than I was hoping, NHfireYJ did you pull out the fuse box or that damn bracket that mounts from the dash & to the firewall that's right in my way ?
Yeah I was just having problems getting the crapper flange up inside the 4" hole in cowl from underneath but with a few choice words and time I did get it in there but now I have to wait till tomorrow to buy a 3" hole saw because my buddies is so dull it just scrapes the surface, hoping to get it all together along with my lebaron hood vents (thanks for all the good idea`s) by next weekend.
With the metalcloak fenders, I had to rearrange a lot of items under the hood and don't have any room along the firewall to drill currently. However, I have a ton of prefilters left over from tractor restorations.
