holley metering block ?s

Fishy68 I haven't been able to locate my # drills. I must have loaned them out
and they disappeared some time ago. I will have to order a set to get back with you
on the sizes used.
That may be the best we can do on these. I may have to get some new inserts and
drill them for a particular use? Although I wouldn't know how to choose sizes myself.
