Hi,
As I said I was told by several Busch/Nascar engine builders here in Georgia that Solid Roller lifters will not last on the street. My motor can't use hydraulic lifters because of the RPM and cam profile but these guys I trust.When I called Isky they said the same exact thing. Apparently the very tiny bearing for the roller just get pounded down over time. MOST of it caused when the engine is idleing. I'm not worried about floating valves as that won't happen as I've got a rev limiter. I'm not saying this to create a fuss but just as a heads up to check it out with your LIFTER manufacturers tech line. Tell him your spring pressure both on the seat and over the nose and ask him how long he suggests running his solid rollers on the street.
It is very easy to change lifters on my motor so I'm going to take their advice as I'd prefer the 11 bucks per lifter to replaceing an LA Billet crank and a very nice set of Olliver rods<G>
Also here is a web site that addresses this issue. I'm not going to use their lifters but check it out...

Also if you do call your lifter guys let me know what you find out as I'm still trying to get a handle on this to.
Regards,
