Being a daily driver you could at the very least step up to a 3:08. Cam Wise stay with a hyd cam this way you won't be have to play around with the valve lash. And something in the RV/towing style or a little bigger. But no more then a 500-550 lift. with a lobe seperation 114-110 anything less will give you a ruff idle and could give you vacum issues if you have power brakes. Now seeing that you motor is pushing over 100,000 now would also be a could time to change the cam & crank gear.(to a non fiber set)It would also be wise to install NEW valve springs.
