Northwind intake/air cleaner in 68 GTO
I stuck my old drop base air cleaner with a 4" tall filter on a Northwind 4150 intake with a wedge spacer on the 850 Holley and it clears the stock hood with ease. That was one of my worries since I measured it with no spacer against a TII with a 1" spacer and it was a hair taller. The TII/spacer set up was close to the hood but the RPM was closer with no spacer.
The spacer on the Northwind is a Moroso wedge that is about 7/8" in the back and 3/8" in the front. The Northwind carb pad is flat unlike the TII & RPM that are angled so the carb leans forward. This is a shot thru the scoop. I used to run a Ram Air setup with the stock intake/Q-Jet and the hood plate is still there. The filter lid fit right inside the plate hole And is about 1\2" from the hood at the carb stud. I always ran a solid mount on the drivers side and it keeps the engine in place. I'm going to graft the outer ring from a single snorkel base to the 1.75" drop aftermarket base for that "sleeper" look. The carb vents are over 2" from the lid with this setup.

Looks great!! Couple of Q's:
A.) why is the spacer a wedge? B.) is that cover (last pic) your cover or do you have a full cover that covers the base? C.) did you powder-coat the Northwind or did you paint it with engine enamel? I am debating whether to keep using my Northwind in my '69 Bird (stock 400 hood). I would like to use a completely stock 400-V8 Poncho air cleaner. Thanks! Brian. |

That lid is just a generic open element part. The stock large diameter lid won't fit through the hole in the ram air pan or else I'd use it. I used Duplicolor engine primer,paint, and clear on the intake and heads. With aluminum heads the paint doesn't burn off or discolor much. I don't know if the 67-9 f-bodies have the hood clearance the a-bodies do. What air cleaner do you have now?

Northwind intake/air cleaner in 68 GTO
It is a K&N low profile (no more than 3" high) with a drop base setup. Ran atop a Holley 750 mech-secondary with a 1" spacer. I want to try using the K&N element in the stock 400/V8 air cleaner. Guess I could always modify it to work (cut/weld up a stock a/cleaner).
I plan to paint the Northwind med-Pontiac blue. |
