Lift off a12 hood on 69 roadrunner

[sc440]

I have a 69 roadrunner, tf240 heads, rpm manifold and Holley carb. I am wanting to buy a 69 airgrabber air cleaner was wondering which base to get (440 or 383) does anyone know if the lid will fit up in the scoop the hood is an original one. If it will a am going with the taller low deck one.

Car has a 440 in it

I believe the 440 base is shorter than the 383.

It is, was wondering if the lid will clear the hood if it goes up in the scoop that will be fine, not sure if opening on back side of hood is big enough for oval lid to clear it.

Why not use the A12 bottom “ box” type? It works for the 6pk

I have a rpm single 4 on there now, does someone make a single 4 version of that air cleaner? Plan is to go 6 barrel with correct style air cleaner just can’t right now. The car is a real a12.

Fiberglass repro’s out there in all configurations of carburetors

Here's what you can expect

A real six barrel hood will have less height at the back of the scoop than the majority of aftermarket hoods.
I'd get the shorter 440 base. There's a reason the 440s are shorter. I'm not sure the 383 will clear at the back of the scoop.
Now, if you had an aftermarket hood.......?

This is a 440 with Indy single plane intake. It's a '70 air cleaner with 383 base but thet doesn't matter - its all going to clear an A12 style hood - original or aftermarket. Your air cleaner will fit with no issues.

Ended up with the 440 base, haven’t had a chance to fit it up yet. With the setup on there now the pentastar nut comes within about 1/4” of the scoop

Yeah well, that thing is nowhere to close to the original style aircleaners. The original bases dropped tthings down over the sides of the carb giving mar space at the top, that thing just sits on top of the carb like a hat that's too small for your head.

lol Yes it’s an old direct connection one I bought in the late 80’s probably about 5” about carb mount.

That’s a 70-72 base

This is a single 4 barrel base pan for 440's

Update on this it didn’t fit not even close,as 33 IMP said real a12 hoods don’t have the clearance in the back of the scoop. I ended up selling it.

Update to my posts as well. The '70 air cleaner assy on top of the Indy intake desn't clear the (aftermarket) A12 hood - not even close. Hits the back underside structure and even if trimmed it would hit at the back of the scoop. Its also too tall and would hit the top of the scoop. FWIW the 383 base has the filter sitting 1" above the carb flange. Not sure of the difference betyween 383 and 440 but seems to me it would only be about 1/2" difference.
