How many owners have noticed engine vibration (around 2500 rpms)?

[89Vette]

Then don't buy a vehicle that has a 75 degree V6 with no balance shaft! The 6VE1 is always going to feel a little uncivilized...

Are you sh'ing me? Motors (cranks) don't have a balance shaft. They have counterweights on the crankshaft.

Should I check my muffler bearings too?
