Do your crane springs work with all the other valve train hardware (retainers/locks)? What makes your high rpm lifter "high rpm"? Are they much different from the stock lifters?
Thanks!

Our crane springs use the stock hardware in terms of retainers and keepers.
Our hi rpm lifters are better than stock, but depending on where you really plan to run in the rpm range (7200+) and for how long, may not be the best suited. But if running up to 7200 these should be fine on most cars.
We currently are working on a PT lifter/conical spring and cam combination which should be coming out over the winter. This set-up should satisfy those owners running REALLY HIGH rpms.
later,

it won't be the ones of the v6, as those are really soft. i ran cranes to 7500 all the time.
What cam are you running, Berry?
