Magnum Adventure
I converted some stock magnum roller lifters to solid for pushrod checking purposes.
Its pretty easy. I just pulled mine apart and stacked some washers in it to take up the slack.
I found with my Magnum cam that had been ground on LA blank that i needed pushrods approximately .040 longer than stock.
Of course your lifters are a ton taller than stock, so you'll mostly be going back the other way.
