As we’ve become aware of Holley now producing variances of the #0-80535-1 even though the part number on the box is the same, the actual carb is marked #0-80535-2 or -3. The newer versions are coming with notched floats (installed) and Jet Extensions included as accessories. Effective Immediately, Jet Extensions are not to be used, neither are extended replacement Jets. Holley Part #36-201 is the Standard-length replacement Jet kit, those are the only length allowed. Accelerator pump cams stamped #336(Primary) and #664(Secondary) are only ones allowed, doesn’t matter colour of composite used, as well no bending of linkage, only adjustment of cam’s is the factory allowed by using stock set screw to adjust cam position. Refer to rule 3.1 below.
To clear up the existing Air Cleaner concerns, we are mandating that: Effective July 12, 2022, ALL25955 will be the allowed base, ALL26086 is the spec spacer and ALL26088 will be the Top. Would recommend getting these sorted ASAP, will be allowing a 2 week grace period to get parts in.
