D4B and LD4B side by side pics
Here is my D4B "Mini Gap" intake for my Florida 273 SB cruiser.
Didn't put a lot of care in removing the crossover as I thought it was only a temporary fix/experiment for the motor as I was installing a Edelbrock Pro Flo (1) EFI as soon as I figured out the manifold interface, which I never did.
Looking at the pic over a decade later, I should have installed a thermal insulation blocker between the hot oil shield and the manifold.
