I had a self proclaimed "expert" tell me that solid roller cams on the street would eventually hammer the lifter needle bearings and seize the roller.
He claims that undel coast/cruise conditions the valve lash can move away from the valve tip and end up between the roller and the cam lobe. This causes the hammering of the lifter.
Is this plain BS?
Are any particular solid roller lifters better for the street?

There may be some truth to it. Most modern street roller grinds use tighter lash settings to ease the stress on the valve train. If I had it to do over again, I would go with a Hydraulic roller. Solid rollers are kinda noisy on a muffled street car. This is my first experience with a street roller and it has approx. 5000 miles with no lash changes or problems yet. Time will tell.  ------------------

My cam grinder has told me that on my "street" solid roller set-up that I should think about replacing my solid roller lifters before 15,000 miles of hard street use. He says it's "real ugly" when they let go, essentially kiss your motor good bye.....------------------

There is an old guy around here with a hopped up street rod from the 60's.
It has an old 327 with dual quads and a 4 speed.
He has som OTS Isky Super Duper Leguerra 555 roller cam in it. The engine has over 50k street and drag stip miles on it. He sets the valves once a year and drives this sh*t out of it.
High quality lifters with adequate lubrication will give plenty of trouble free miles.
Econo roller lifters like the Herberts, I wouldn't drive around the block. ------------------
