The standard Z-code 390 rose to 315 hp and the Q-code 428 offered 345 hp; the factory manual identifies both engines and no manual transmission.

The standard 390 was rated at 315 hp.
The 345-hp Q-code 428 became an optional Thunderbird engine.

Worth knowing

Notable

Living with it

Reliability & ownership notes

Decode the VIN engine letter before ordering powertrain parts: Z identifies the 390 and Q identifies the 428.
Inspect sequential rear turn signals, vacuum accessories, and convertible-top operation where fitted.
