Anyone here use Schubeck lifters ?

I damn near tried a mushroom lifter this time. But, in the end, Jim didn't think it would be a big difference because I was already opening the valves about as fast as we thought the heads could keep up. We both may be wrong but I hope not.

Well they sure had their day in the sun, no doubt. I have a friend who wants to build a 440 with a mushroom setup just for the nostalgia, sling it in a 73 2 door Monaco and go surprise some people on the local strip. I am not "completely sure" it ain't gonna happen. lol
