Man! Tight squeeze! Looks like I might have an inch or so to the hood frame from the top of the choke box. Yikes! What are using for an air cleaner? I was going for an airbox type fresh air plenum but now I'm thinking I'd better get a 2" drop with a K&N filter lid. I asked the question last summer when the engine was out and I could only guess what space I'd have but now it's go time!

I have a drop base with the foam lid. Both are new, tried to get them to work with a very tall single plane couple of years ago but was too tight. Ended up switching to a dual plane dual carb setup, and it came with a filter. These have been sitting on the shelf since then. $50 plus freight.

you can also gain a little more clearance by putting spacers between the k member and frame. Dont want to drop it too much or you can have ground clearance problems, or steering component clearance problems.

there won't really be a ground clearance problem , the K frame and components bolted directly to it will not get closer to the ground , but you will put a side/bending load on the end of the torsion at the rear Xmember

Lose the choke and choke tower , the filter lid doesn't work for bleep if it's pressed up against the underside of the hood.
Another reason I prefer low decks , you get an extra 3/4" clearance ... 
I was wondering who the first person would be to recommend milling off the choke tower. You win, John.  It's a last resort. Don't want to mess up a good Avenger if I don't have to and I would REALLY like a choke. I really wanted to build a 451 stroker but this 440 presented itself as a less expensive alternative. Plus it looks awesome. 
is there such a thing as a good running avenger ?
Does proform make a main body for the avenger series ?

68 Charger, 440, RPM, Mighty demon carb. Hood clearance same as what you show in those pics. Wasnt any better with an edelbrock 1407 I used to run. I use a stock 68 unsilenced air cleaner. Due to the odd diameter of the stock mopar lid, the usual suspects for drop base won't work. I had to buy a complete ford motorsports air cleaner on ebag. I just used the drop base from it. plenty of clearance now. this was years ago and maybe someone has come up with a drop base thats the right diameter. As an aside, I ran a holley projection for a while and that TB was definitely shorter than a normal carb. I was able to run the standard base that came with the unsilenced.

Dogdays, thanks for the positive input. I respect JohnRR's knowledge and opinion, although I must say that if I did everything he told me I should do, I would have $50K involved in my car and it would be bulletproof. DKN 1997, Rarefish and 383man, are any of you running a holley with choke tower? If so, how's the performance with that drop air cleaner? Since we are going there, have any of you removed a choke tower? if so, what did you use?
