if you have a block suitable for the oem hydraulic roller lifter then these are a good and cheap option (magnum or LA roller block). I did not find their limit up til now, 6800 rpm with a 250° / .620" lift cam (1.6 Rockers). Possibly a solid roller would make more power, but for a street / strip toy i like the hydraulic rollers.

Thanks for this, of corse various factors at play. I was always curious of the limits of those lifters, I don't believe I've spun mine past 6300 maybe 6400.
