Default ok what is my problem.

Ok, before i get home today to check my 69 350/350 have had it 3 months ran ok, did some checking. It had the wrong spark plugs autolight, replaced with ac r44s seem to run better . Yesterday i checked the timing, it was off 4 deg after, set it to 4 deg before reset carb and idle to 750 its a stick. So it ran great after that, real good. This morning going to work, the take off and through the gears good, but around 45 through 65 i have a vibration throughout the car and the exhaust sounds muffeled. But the car idles ok and does not sound like its missing. Any suggestions.

check the distributor timing weights and springs to make sure they are working correctly. Check the vac advance canister works, is on the correct port, no vac leaks. Make sure the dist cap is not tracked up or cracked..
Make sure the choke pulled off.
Basics first, make sure whats not, then look for what else it could be
