Would not be surprised. Fortunately, no one is advising the OP to go to 10.5 CR, just move from 7.9 up to the low 9 range to get better low end torque. For daily driving, good torque makes for a good response. The OP is going to need all he can get with the 268 cam, as that is going to degrade the already low CR to an even lower one and that will be felt as 'bogginess' at low RPM's.
