I recently came across some L-Z carbs (model 06H, with Lincoln Zephyr inscription) that have a 4 bolt base and will fit on the 49-51 Merc intake. Has anyone had experience with these? Flow rates compared to stock Merc carb? Appreciate your thoughts and advice.

According to my old Holley manual, it shows they made the Holley 06H LZ carbs with both three bolt and four bolt bases. They both have 1" venturi's , which is only slightly larger than an old Holley 94. I would guess the 06H Holley carb is maybe 200 CFM or so. The Lincoln Zephyr V-12's were small displacement engines for the number of cylinders they have.
I have no idea if they have a vacuum port for the distributor on th Merc engine you have. Or if the vacuum signal is correct for the factory Loadomatic distributor in the Merc engine.
