Hoods vs. air cleaners with 2F

A new-to-me 1972 FJ55 has a 2F with header and holley carb. I wish to go back to stock manifolds and air cleaner. I have the "flat" hood. Can I use 2F manifolds and oblong air cleaner with flat hood? Is there any combination that retains flat hood (like 1F manifolds) or does 2F dictate "bulge" hood? (That's my guess as to why the hood change occurred?

Thanks,

Gerry

This was brought up about six months ago.

The hump in the hood is for the air cleaner.

Last I looked, an F and 2F intake were basically 'flat' from the head. So swapping there won't make a difference.

The last time I looked at a 2F, there was a rosin 'spacer' with a large vacuum port on it. I want to say 3/4" thick. I never looked close at an F.

I don't think their is a difference in height of carb.

So then does anyone know if 1F manifolds and air cleaner (big round tub) off to the side would fit under the flat hood?

"55" project took major turn in last year of work. Pictures and description to follow shortly via proper introduction. Thank for help!

Thanks for the photos. That's the air cleaner I meant. Bob, it looks like your vehicle has bulged hood correct. Liljohn, your hood must be flat on a 72 correct?

Vehicle I purchased has 2F motor, intake, and holley carb with headers. I do have a separate 1F manifold set and the round style air cleaner. I just don't know if 1) there was anything on that side of the 2F that is not on the 1F and would interfere and 2) if they would go under the flat hood.

Thanks for any help.

72 started life and came into my possession with a flat hood. It has since been upgraded to a bulged hood.

I want to say the 1F air cleaner used a head bolt to attach to the block. I'm not sure if the alternator on the 2F would interfere.

Are you sure the 1F air intake throat will even work on the Holley?

The Holley is on the vehicle as purchased through some kind of adapter, 2F intake, and headers. I'm trying to eliminate neaders and Holley and go back to stock manifolds while retaining the flat hood (if I can) and 2F. I have 1F manifolds and carb but they are in storage and haven't yet been located. In meantine, I'm trying to figure out if I will need 2F manifolds.
