Z-PAK Concerns
what do u guys run your z-paks at? it calls for .050 - .070 clearance. that seems like an *** load of clearance. i was going thru some threads, in the search, and most like to run their 4l60e 3-4 clutch pack @ .025. though i'm not sure what clutches being used but guessing BW HE's. i'm thinking about running the same. i measured my 3-4 clearance and it came right in at .070. it is in a 98' 4l60e, 9.5" 3K stall in H/C LS1 Z.
on another note, how large can you go on 3rd feed with the sonnax servo check valve + vacuum modulation? .130 safe? 4th feed is too small on the transgo HD2 IMO, but how much larger is safe? thanks alot.
