I agree that 52 is probably overkill for a bolt-on mod... for that matter, I
believe that F&B's test revealed no significant gain on a 5.9L from opening
up the bores from the stock size, as long as you remove the stonehenge
blocks (shave top), polish the bore and thin the shaft significantly... My
truck is a 4x4, so I don't want to sacrifice any low end... I have the 5.9L,
but I prefer the F&B stage 1 since everyone else opens up the bores... I
wonder if they've done any testing to verify if that actually improves
performance, or if they just started by opening up the bores...
I believe it's very easy to go too far witht this mod... and cost yourself
too much low end, without much gain in top end (over a modified, but
non-bored T/B)
(sound of soap box sliding away)
