I have a 406 with a Lunati 249/255@.050 624/640 solid roller and 210 AFR heads and the springs are 225 at the seat pressure and 600 open pressure and the engine will be used mainly on the street. I was wondering which Solid Lifter I should get; Do I need a pressurized Lifter(Lunati(morel), Isky, Comp cam, ect...) or will a none pressurized Lifter work(Lunati)?

 

you want something with pressurized oiling. i have the crower HIPPO lifters and they have been great.

 

Morel's seem to be the accepted best by high end builders. They are also sold under other brands, comp sells them for top fuel, howards racings top end lifter is a morel, as well as a couple other brands.

Isky Red Zones get a lot of good reviews, and so do the crowers.
