The 335-hp 455 High Output was the only engine in the '71 Trans Am. To create the 455 HO, ontiac borrowed the cylinder heads andcamshaftfrom the previous year's 345-hp Ram Air 400, nd added the aluminum intake manifold from the rowdy 370-hp 400 Ram Air IV.
The 455 had less advertised power than the '70 T/A mills, nd it couldn't wind as high. But at 8.4:1 compression (compared to 10.5:1 for the retired Ram Air 400s), t could run happily on a wider range offuels, as less temperamental than the Ram Air IV, nd with 480 lb-ft oftorqueat a usable 3600 rpm, t packed a real wallop around town. Plus, t had four-bolt mains for strength.
