68-69 Novas share a similar front subframe with the Camaro of the same years, however...when the bigblocks were installed into the Novas, the torque on launch caused worse spring wrap than on the Camaros.This would cause sketchy handling. The Novas of those years only had monoleaf rear springs and the rear shocks were mounted on opposite sides of the rear axle from each other.(one was mounted in front of the axle, and one was behind). Additionally, when the 427 was installed the lack of frame connectors would allow the body to twist so bad on a hard launch that the windshields would either crack, or even pop out of the body. This is why they were considered so "lethal".
