Intake manifolds

Once again looking for input, this time on Intake manifolds. Im interested in hearing from anyone with an aftermarket in take on a 65 to 68 Eighty Eigth or ninety eight. Especially single planes if anyone has one. These cars have a prettty low hoodline. Wondering what others have been able to fit without hood interference. Currently i have a performer, so i already know they fit.
Thanks in advance
Pete .

@Oldsguy had a 69 Delta 88 with an O4B Edelbrock intake manifold in it.

The O4B was a dual plane intake so the basic geometry was similar to the cast iron one Oldsmobile had in that respect. Dual plane intakes generally have a lower profile than single plane ones so that fact combined with the availability and price point was why I used the O4B. It performed well and I experienced no hood clearance issues when I used an aftermarket air filter housing. Since your request ended with 1968 year, I am not sure if this information will be helpful but I don't recall that much difference in the hood profile.

Apologies, I thought that O4B intake was single plane. I recall that Oldsguy bought it used from one of my instructors.
