Seems most of the replies indicate that velocity stacks are absolutely
necessary... however, I did get a desenting opinion from Steve Ford
(formerly of Part-is-parts fame) a while back.. stating that the VHB29's
are so crude and inefficient that venturi 'performance' matters not in
the least.. of course, I'm not qualified to have an opinion, so gets me
off the hook (I do run 'em with my K&N's)......

Hi, Andy. My early '69 Ambo has small velocity stacks
on the carbs. I have Uni filters that fit onto them
pretty well without any modification.

doesn't have velocity stacks, but my eldo does what
exactly is the purpose of these thangs? will they
improve the air-flow? make her run cleaner [stronger?]
seems like a while back, Mark E. said that he had
several sets, some machined down to accept K&N's.
guess i shoulda paid more attention. tia, andy ")
