I went with a 9" x 2.25" K&N filter, topped by a K&N X-Stream top. The carb (Holley Street Avenger, 770 CFM) is installed on a 5° wedge spacer to better align it with the angle of the hood and scoop. The manifold is an Edelbrock Performer 460 (Not RPM). All good with about 3/8" of clearance.

The only modification I made to the base of my air cleaner was cut about 1/4" off the lip that fits on top of the carb. I'm speaking to an installation in to a Factory Five, which, may be different than a Backdraft or West Coast. IF you stick with the stock 'crate' engine specs without getting too extreme, I think the 850 double pumper will over feed the engine....it did mine and one of the reasons I stepped back to a 750. Also, no choke...I'm in Missouri, and have never had trouble starting mine without a choke. More headaches in my opinion as I used to have an electric choke, but removed it after it got stuck on me a few times.

That does fill the engine bay. It appears much more so than an FE. Is the hood "standard" or is the scoop extended?

It's a 'standard' scoop, though I have toyed with the idea of a wider scoop so I can use a 14" filter, mostly prior to going to my current setup. Some of the European replicas (e.g. DAX) use a wider scoop - not as large as the one on the 'Super Snakes', just wider, perhaps a bit higher and a big less rounded.

FWIW, I see Shell Valley has a large scoop in their catalogue - it's listed as 31.5" long, 18.5" wide (presumably flange to flange) and 3.5" high. It also looks like it's more rounded, more like the original style than the slightly angular DAX scoop. Cobra Replica Hood Scoop

MNM - I think the car sounds great and was a primary reason i bought the car. The thing is, with a crate motor, you get a warranty and safe horsepower, meaning, the engine is capable of so much more, but....why? Again, depends on what you want to use the car for. One of our former club members had a backdraft with a 351 bored and stroked to a 427 which also sounded great. Up to you, but two cars I've seen with big blocks in them, mine (a Factory Five) and a friend's Superformance. The Superformance accepted the big block perfectly.

Here's my 521 with Webers...

The carb is the quick fuel ss-750
The intake is the performer 460
And the air cleaner is the stock hill type 10"
I still have 3 inches left from the cleaner stud
