1974 Nova Parts and Restoration Information

The 1974 Nova was the final year for the third generation Chevy X-Body. It featured minor changes such as larger parking lights, a new bowtie grille emblem, and new larger bumpers that help in minor impacts.

The SS option was slightly revised with new stripes now on the hood and trunk. The tail light panel was no longer painted black but the window frames and sport mirrors were. The Powerglide transmission was also replaced by a lighter weight version of the 3-speed Turbo Hydra-Matic 350. The 307 cubic inch engine was also dropped as an option which left only the Turbo-Fire 350 as the V8 option.

In celebration of the upcoming bicentennial, Chevrolet created the Spirit of America Nova (RPO-Z51). This one-year option included special red, white, and blue trim, stripes, and interior. There were roughly 390,537 Novas built in 1974 and only 14,463 Spirit of America Novas were ever built.
