Dual Plane vs Single Plane Manifold with TBI

If you don't want to hack up your LD4B plenum divider you can use a carb spacer to give the same effect as cutting down the plenum divider.

Can experiment easily this way without doing irreversible damage to your rare LD4B intake.

Good Luck

Think the D4B 4bbl intakes were for the 273s, they have different angled bolt holes.

Can ask @toolmanmike as he has worked with 273s and knows them. Some have re-angled the bolt holes on the LD4B so that they will bolt up to the 273 heads.

Not sure if the newer 302 heads will bolt onto the 273 block? If so then your LD4B intake will bolt right up to those.
