Default 1900 RPM=Violent fr. to re. shaking while driving

This happens right around 1700-1900 rpms in basically any gear. It dosent feel like a normal vibration just a front to rear shaking. The engine is stock minus boltons. It does have a b body cam/short block in it on the stock tune with roller rockers and a lt4 km. The flywheel has also been replaced with a really cheap autozone one. Whats weird is it dosent happen all the time, but it does almost always happens when its cold.
