Grumpy, What Cam Manufactures Do You Use?

[Grumpy]

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 )

BUY A FEW BOOKS ON ENGINE REBUILDING AND PROPER ENGINE ASSEMBLY
AND READ THROGH THEM CAREFULLY,
ITS MONEY VERY WELL SPENT!

anyone who has extensive engine assembly experience will have at some point had an experience related to a failed valve train component,
and ID bet the vast majority of the guys who had a cam or lifter or rocker arm ,
valve spring,
component fail, were certain to blame the failure on a defective component,
when the truth is that in many cases the person installing that component failed to carefully check clearances,
check the valve train geometry or provide the correct lubrication, or follow the manufacturers installation instructions.
yeah I've had guys ask for help when their muscle car or corvette engines had serious issues,
and I've done more than my share of screwed up engine autopsies,
guys install a cam, never checking the valve train clearances ,
and invariably, so & so brand cam SUCKS because it failed ....
the fact the guy never checked for coil bind,
rocker to rocker stud clearances or piston to valve clearance.
or even ever applied moly lube or has a clue how to properly adjust valves,
and has never seen a degree wheel,
has zero to do with the component failure????
yeah, so & so brand cam SUCKS because it failed
I have got to point out , that in my experience ,
its far more likely that the part was not properly installed and clearances were never properly checked,
I've had guys tell me they bent several push rods, or busted valve springs..
but it never occurred to them that there must be a reason
...and checking clearances or using a degree wheel and dial indicator...
.NAAAAA, thats not required
hell you just line up the dots and your good to go!!!
yeah the valve trains stock, the orriginal valve lift is .450 ,
and the new cams lift is .615, but thats only a change of a little over 1/6th"
what could go wrong???
