as it always has quality is at least somewhat related to price, and the generic stuff sold is generally not top quality.
and you can bet your last dollar safely that if you fail to use the same manufacturers cam and lifter combo or ignore his valve spring load rate or clearance suggestions, or fail to check clearances or properly install a cam, your warrantee is worth zip/nada!now I've certainly used plenty of cam and lifter kits from manufacturers that you might not of heard of frequently mentioned.
like
erson,
lunati,
howard,
isky,
engle,
crane
or
crower
the last three engines I built used ERSON CAMS,
simply because they had the specs I wanted,
and I have had zero issues with those cams
(btw two were hydraulic roller SBC one was BBC )
