Default Re: Flat tappet lifter failure

Bubski is thinking like OK let's go roller for all !! Since this is "stock" wouldn't it be in the best interest of the rules to stay "stock" ??? So !! Ffford n Chevy "stock" rollers have a .700 lifter wheel diameter !! Every aftermarket roller is .750,.760 not really "stock" where you're supposed to abide by the "stock" rules !! Such as lifter diameter which is enforced but cam bearing diameter is a gray area !! Let's get even more into it !! .250-.280 lobes are not in every cam companies master list !! But Bubski's sure for a few bucks more they'll make a few concessions !! Sooo !! Now you can have a universal roller cam rule and make everyone with a roller go to stock roller diameters and spend some more cash on a set of lifters that are now legal !! However Bubski doesn't know of any race lifters at stock roller wheel dimensions !! However Bubski is sure a few will step up to the "cause" and kindly beat YOU over the head with a "stock" diameter roller lifter and accompanying valve train package !! Maybe it's time to break out the "lifter tru" and reevaluate your camshaft and valve spring choice !! SS has unlimited cam lift and the like !! Show Bubski a 305 with 1.250 lift !! It's not feasible and a BBC with an unrealistic camshaft is also unfeasible !! Sometimes you gotta work within the parameters you're given !! Cheers !!
