Gen VI BBC lifters
Does anyone now what the deal is with hyraulic rollers in the Gen 6 BBC? Crane says extended travel lifters are needed for cams over .570" lift. What I am curious about is why GM uses the stock 7.4 vortec lifter in the zz572 with a .631" lift cam?
I am building an engine on the short deck two-piece main version of the block the zz572 uses. Are the lifter bores closer to the cam in the bowtie blocks? Crane sells their version of the stock lifter for $250ish the Crane extended travel lifters are $500ish.
Any clues?
Thanks
