1971 Pontiac GTO

The Pontiac 1971 GTO 

Had another humble facelift, this time with wire-network grilles, flat guard bars on either side of the grille opening, all the more firmly separated headlamps, and another hood with the double scoops moved to the main edge, not far over the grille. General length became marginally to 203.3 in (5,164 mm).

For Pontiac 1971, the standard backside was an open 10 jolt.

Positraction 10 jolt backsides were accessible as a choice on 400 CI motor prepared GTO's, while every one of the 455 CI GTO's were accessible with a 12 jolt open or discretionary 12 jolt Positraction backside.

Another corporate order, went for planning GM for no-lead fuel, constrained an in all cases lessening in pressure proportions.

The Ram Air motors did not return for 1971. The standard GTO motor was still the 400 CID V8, yet now with 8.2:1 pressure. Force was appraised at 300 hp (220 kW) SAE gross at 4,800 rpm and torque at 400 lb·ft (542 N·m) at 3,600 rpm. It had 255 hp (190 kW) SAE net at 4,400 rpm in the GTO and 250 hp (190 kW) SAE net at 4,400 rpm in the Firebird.

A motor choice was the 455 CID V8 with four-barrel carburetor, 8.4 to 1 pressure proportion and 325 hp (242 kW) at 4,400 rpm, which was just accessible with the Turbo Hydra-matic TH-400 transmission. It had 260 hp (190 kW) SAE net at 4,000 rpm in the GTO and 255 hp (190 kW) SAE net in the Firebird. This motor was not accessible with air instigation.

The top GTO motor for 1971 was the new 455 HO with 8.4 pressure, appraised at 335 hp (250 kW) at 4,800 rpm and 480 lb·ft (651 N·m) at 3,600 rpm. It had 310 hp (230 kW) SAE net at 4,400 rpm in the GTO and 305 hp (227 kW) SAE net in the Firebird Trans Am or Formula 455 with air instigation. The 1971 Pontiac handout pronounced that this motor created more NET pull than whatever other motor in its history. That would suggest the 400 CID V8 Ram Air motors had under 310 hp net.

Engine Trend tried a 1971 GTO with the 455, four-speed transmission, and 3.90 hub, and acquired a 0–60 mph time of 6.1 seconds and a quarter mile increasing speed of 13.4 seconds at 102 mph (164 km/h).
