I feed my RamJet 350 via the L-88 hood intake. https://www.corvetteforum.com/g/album/6185135

Now THAT is very slick! Do you have any pics of the internals of your air filters? From the pics it looks like you have two internally mounted in the ducting.

Did you custom make the intake adapter as well? Fiberglass?

Would love to hear more.

I'm headed down the same road but you're ahead of me at this point. I plan to order a new 383 w/ Edelbrock Pro-Flo 4 XT system fairly soon. Please post back if you come up with a good solution.

I’ve seen your photos before somewhere - very interesting! I’d like to learn more about the setup and what you’re seeing for results. Is there a thread somewhere or would you mind sharing the backstory and how you came up with that solution?

Any input is greatly appreciated! 🙂

Okay will do! I need to focus and do a bunch of research but I’m thinking a GTO Vararam system could be the best and look the cleanest like the LS post above. Stay tuned.

I just got the Vara Ram .. Fits well .. All I need now is my intake TPIS Mini Ram 2 and the rubber hose to connect the T/B to the air cleaner

Look where the c5 filter fits in front of the radiator. I borrowed a friend's c6 factory intake and there's no easy it was going to clear the hood when open. The c3 hood is very close to the radiator/ac condensor when open. You'd have to look at getting some different hinges and method of lifting to run something like that or just not open hood all the way. Plus you'd probably have to cut your upper radiator support. If you don't run an ac condensor then that would allow you some extra room too.

Another option is you might be able to have height of radiator cut down for room over top.

Ya they did , I got it and the ports were so small I would have lost hp and I sent it back lol .. The Mini Ram2 is on the way instead 1206 ports . The Pro flow was more a 1204 or stock intake port ,And if I tried to port it to 1206 I would have burned through the runners

Dustin James I probably fabricated that about 15 years ago. There is a K&N air filter in each flowpath. I glassed the ABS onto the bottom of the hood and then used that hvac ducting to line it all up. I thought about making it "pretty" but I kinda liked the "industrial" look. The ducting comes apart in case I need to clean the air filters. That's all the pictures I have, but as you can see there isn't anything special about it other than the patience to get it to line up.

Works fine - get nice cool air as measured at the air intake probe. I am running EZ-EFI 2.0 so I can actually read the temp. PM me if you want other pics.

Backstory is that I had an L88 hood from when I had previously installed a Edelbrock 7101 and I used to have a Holley Pro-Jection throttle-body analog efi on top of it.... ran quite well really for analog fuel injection. So I had room on top. I just thought I'd try it to try and use the L-88 hood intake path. Seems to work well. Last thing I ever concern myself with is hot underhood air.

About the intake adaptor- that is a cut-up disposable propane bottle that my neighbor had thrown out. I tried several other contraptions before I found the neighbor's pile of used of propane bottles. I cut it up to match the ABS ducting and I painted it. I also brazed on a threaded fitting to install the Air Temperature Sensor.
