I don't qualify as a 13 second Bullitt owner, so my post may be meaningless, but I'll get the replies started for you.
How many miles are on your car now? I ask because mine produced similar MPH numbers before 1600 miles. My second run down the track was 75.70/eighth and 95.90/quarter. Your 60' and 330' were pretty decent though.
Now, some cars have run fast right from the start, mine didn't. It is possible that your's is like mine. By beating on the car more and getting some miles on it, it ran over 79.xx/eighth and 100.50/quarter at about 3000 miles.
