J&B Weld Holley Carburetor Mods!? | Will It Flow More CFM | Holley Performance | Modified Carburetor

Holley 600cfm XMC Carburetor Project! J&B Weld Mod Edition 👌

so here it is! the end of our step 2 modifications to our holley carburetor flow bench test muel. so first of all we completely filled this thing full of J&B Weld Epoxy and ported it out to a fairly streamline and radius entry. then we worked on the straight leg boosters by removing the cross bar from the middle, sharpening the edges, and flaring out the bottom to hopefully gain more cfm while remaining booster signal.

finally we go over the accelerator pump discharge circuit were we drilled and tapped it to accept an adjustable air bleed. and as for the air bleeds we addressed moving them to the metering block itself or making a new path out the side of the carburetor main body for it.

so all in all what do you think it will do? flow more? flow less? well it is getting shipped to @josephnowak to find out!
