Thanks for the pics, hood is already done, not sure I can bring myself to cut it, Thinking of fabricating a flat cover for the breather so I'll be able to get the hood closed.

That might not work, carbs sit too high in the baseplate. If you cut the hood, slip a piece of sheetmetal between the 2 layers and use a whizzer or dremel. If it has stock glue in the way cut that first with a sharp knife. If the glue is real nasty, glass guys have a tool the fits a sawzall that is thin like sheetmetal that will cut it. Reglue with 3m nvt, or plain silicone. Do not use fusor type products or it could telegraph thru the hood. Sorry for all the bad news.

I've read on this forum that some people install 1/4" or thicker shims between the K-member and the frame rails. I almost had to do that with my Shaker hood 'Cuda due to running Indy EZ's, but I was able to get away without them. It is tighter than stock though.

You can see where the Shaker bubble rubs on the nearest corner in the pic. My '68's air cleaner rubs on the hood mat pretty good too, but it doesn't seem to cause noise or vibrations. The hood pretty much rests on the air cleaner ever so slightly, so I have engine limiting straps on both cars so it doesn't break anything..

Having some metal fly cut off the carb flanges was another consideration to lower the height of the intake, but I didn't need to go there.

I would like to be able to run the taller K&N filter on my Shaker, but it just won't fit in there without modifying the shaker bubble.

Here's how I solved my clearance issues with my old 70 Charger 440-6 w/ stage VI heads and meth/water plates.

Thanks jbc, didn’t realize a K&N is different height than a stock CA332/repop, that might fix it. I have the K&N, anyone know what the height difference is?

That should clear...something isn't right. It is super duper tight in there, so absolutely no carburetor spacers or heat spacers, but otherwise it should clear ???

The 6 Pak K&N filter comes in 2 different heights, 2" and 3" tall elements, the factory OEM element/repop CA332 is 2" tall...

Are you running factory style motor mounts? or aftermarket?

It’s the 2” K&N and I put in the Schumacher stock replacement motor mounts. I’m not using any carb riser plates.

Where exactly is the hood supposed to be trimmed or "cut"??????

Maybe on the Superbird's where they use a flat Coronet hood (examples earlier in this thread), But on the Bees and R/T's with the power bulge hoods they are NOT cut from the factory. Something is a miss with your set up Pete. Maybe try and adjust the motor mounts, but as mentioned above the K-frame can be spaced down for additional clearance, but you shouldn't have to do that. Is the air cleaner base correct?

That's why I asked about your mounts, I suspect the Schumachers may be your culprit?, others have complained about them in the past when used on fresh air cars raising the motor higher causing seal/air cleaner interference problems, and the 68-70 B body stock hoods/braces/pads are VERY close when running an RB sixpack

Thanks Jeff, air cleaner base is correct, interesting comment about the Schumacher mounts Dayclona. Just starting a stretch of work, I’ll follow up on that when I’m back and post an update.

Did you look at the yellow 4bbl hood, then the 2 orange 6bbl hoods? They are cut on 6bbl cars, you cut the whole center brace out, dead center, front to back. If he has a flat coronet hood it will have to be cut out to fit. Did a little internet search and the original 6bbl twin scoop hoods were cut out also, if you look up in the airbox there is no brace.

Correct. A twin scoop hood IS a flat hood. The power bulge hood is raised up in the center.

Thats true, but did it use the same lower stamping? I dont recall seeing a 6bbl car with a power bulge hood but could be wrong. I have 2 70 power bulge hoods, I will dig them out and compare it to a superbird hood, then we will know....I am betting same lower stamping, cut out if it is a 6bbl, but could be wrong. Be a few weeks unless someone else has a pic of the underside of a power bulge hood 6bbl car.

The power bulge hood does indeed use a different inner skin, it also has a center brace front to rear, I can't tell if it would clear a 6bbl.

Ya I saw that, I do not believe that they cut the center out to make it easier to make a sbird hood...that makes zero sense, unless it makes it easier to make a dual scoop superbee hood too. That brace is nowhere near the superbird mods. What we do know is the op has a hood that will not close, the car I worked on would not close until the brace was removed, your car has 6bbl no brace, my 6bbl car has no brace....my hood did say nascar on it after chemical stripping. Find me a pic of a superbird with a 6bbl, no shims under k-frame, and an uncut hood and I will believe it.

Third rock from the sun.
Think you’re on the right track 4406bbl. It’s been a 4yr restoration so had to dig back through the info/memory. My original power bulge hood outer skin was good enough to use, the inner skin was bad. I was able to buy a 70’ Coronet flat hood that was in very good shape and replaced the inner skin on the power bulge. Thanks to all your pictures it’s clear that they are two different inner skins. On that center brace the “trough” in the middle of the brace is towards the top of the hood on an original power bulge hood, on a flat hood (mine) it is towards the engine bay contributing to my interference. I’m still not sure it’s the only culprit but it’s a big part of it. Now my brace needs to be cut but I’m considering if removing just the bulging trough will be enough to give me clearance. Will update as the work progresses, great discussion, thanks for all the your posts!
