oui ces dernierre annee du 455 le 400 t/a de annee apres etait plus vite

The first sign of performance arrived on February 4, 1975, in Car Distribution Bulletin 75-47. It simply stated that a 455 four-barrel engine and four-speed manual transmission would be available on the Trans Am in mid-March. More detailed information came on February 17 when Sales Information Bulletin 75-7 was issued, outlining the contents of an optional 455 H.O. package for the Trans Am. Several more weeks passed before CDB 75-62 was issued on April 14 announcing that option package UPC L75 listed for $150 and was available in all states except California. It added that orders would be accepted immediately, and production was expected to begin around May 12.

The Trans Am shared the same 455 four-barrel engine rated at 200 hp at 3,500 rpm and 330 lb-ft of torque at a lowly 2,000 rpm with other A-, B-, and G-body applications. It had an 067 camshaft with 273/289 degrees of duration and 0.407-inch lift, an 800-cfm Rochester Quadrajet, and an HEI distributor. But unlike those used in other applications, the Trans Am WX-code 455 had a carburetor and distributor that were calibrated slightly differently and a specifically tuned exhaust system for improved performance.

Backing the 455 was a Borg-Warner Super T10 four-speed manual transmission and a floor-mounted Hurst shifter. Carrying UPC M21, the close-ratio gearbox had a First-gear ratio of 2.43:1, and was the same unit available with the 400ci but with an 11-inch-diameter clutch disc to accommodate the additional torque output from the long-stroke 455. Power was transferred to the pavement through a limited-slip, 8.5-inch GM 10-bolt differential with a 3.23:1 gearset. No other transmission or rear axle combinations were available.

The package was carried over for the '76 model year. It was, however, renamed "455 Four-Barrel Performance Package" and "HO" was subsequently removed from the Shaker.
