Here are my measurements from the fronat and rear valley pan seal of the block. on the first dimensions. Second set to a flat valley pan right at the carb pad.
Northwind 7 5/16 / 7 3/8 Carb pad 7 3/16 / 7 3/16
Victor 8 9/16" / 8 9/16" Carb pad 8 1/2 / 8 1/2"

So about 1 1/4"

I got a Northwind 4500 form Butler a few months ago but had to wait a month or two for it to get to them. My IA/Camaro with a 3" cowl with E heads and a Victor is close with a 4150 but I can get a drop base air filter on it. Not sure it would with a Dominator and for sure with High Ports and Victor.

Skip, what is the port height on the 'As Cast' Northwind intake ?

My air cleaner assembly goes up inside the hood scoop. With a HP950 carb I used a Victor intake with a K&N 9-inch diameter filter that was 2.875" tall and with it the 9-inch diameter X-stream filter top. In addition I had the Victor intake carb flange milled down 0.650" for extra clearance. On my 505 dyno testing indicated the milled intake gave up about 8-10 HP at peak power rpm. With 660 HP I was not worried about the loss ! For track use, just remove the air cleaner.
Butler has done the same on a 535 combo on a Victor intake for use on a functioning shaker assembly, it gave up about 15 hp on the dyno.

This all said, I run Edelbrock cylinder heads. Not the taller HP heads.

(Since then I have converted to direct port fuel injection. With the throttle body in place of the carb the air cleaner assy still goes up inside the scoop.

Can you post some info regarding your fuel injection set-up? Btw - I love how you did your interior and cage. I’ll be switching mine from black back to the original deluxe bright blue. Best looking interior color IMO.

Great info!
