OK, OK, I went and found it, I didn't mean be ripped or stay ripped, just that BF % DOES make a difference, but DOESN'T mean you won't GAIN fat in the process of adding LBM. I was assuming blood_drinker was referring to starting body fat percentage:
A cut and paste from Dave Greenwalt (the Powerstore) regarding gaining LBM.
"Weight gain experiments
In subjects overfed, initial body fat level is
important. In fact, in a few studies, subjects with low
initial levels of body fat (10kg) gained about 70% of their
weight gain as lean body mass (and only 30% was fat mass).
These data also show that in subjects starting with 20kg and
40kg of body fat, only 30% and 20% of the weight gained was
lean body mass (while 70% and 80% of the weight gained comes
from increased fat mass).
From overfeeding studies, it is clear that lean
individuals gain less fat and more lbm when overfeeding when
compared to their fatter counterparts. In fact, this study
generated a predictive equation indicating that the ratio of
lean mass gained to total weight gained is related to
initial fat mass by the following equation:
Lean Mass Gain / Weight Gain = 10.4 / {10.4 + initial fat
weight (kg)}
Therefore for someone who is 92kg (200lbs) and 5% body
(4.6kg fat), about 70% of the weight gained during an
overfeeding phase can be expected to be lean body mass. In
someone who is 92kg and 10% body fat (9.2kg of fat), 53% of
weight gained will be lean body mass. So perhaps a good
idea is to only overfeed when relatively lean. If you are
200lbs and around 10-15% body fat (14-18% for females), about half the weight you
gain will be fat and half will be muscle. If you try to
gain when fatter than 15% (18% for females), much of the weight you gain will
be fat mass.
Since the equation seems to work for dieting also, just
switch it around as follows:
Lean Mass Loss / Weight Loss = 10.4 / {10.4 + initial fat
weight (kg)}
While not flawless, these equations are handy tools for
estimating how much lbm and fat you may gain or lose when
underfeeding or overfeeding. Remember though if supplements
that preserve lean body mass (like the ECA stack) are used
during dieting or if supplements like creatine or drugs like
androgens are used during overfeeding, these ratios may
change."

The subjects were not BBs, and were not following a clean "bulking" diet.
However the general principal is sound. By decreasing you carbs and increasing your protein compared to those test subjects you can minimise fat gain but you're still gonna add a some more fat before you reach your goal.
