340, hydrolic lifter 273 rocker solid pushrod no oil hole

I shim the lifters to have maybe .010 to .015 travel = Just to have a little cushion.
We run Schubeck lifters with the hard Ceramic pucks on the bottom. If we run them
solid = They tend to drop the pucks out with catastrophic engine ending results!
Plus the camshaft profiles I run (huge duration and stock lift) that Isky built for me
years ago are no longer available from them any more. My son in his Demon runs
tool steel lifters and a billet camshaft BUT it is a couple thousand dollar deal to buy!
