In direct competition to Pontiac's GTO, Plymouth brought out the Hemi-powered GTX. More of a luxury vehicle with an awesome powerplant than out-and-out racer, the car nonetheless dominated on the track or street. The Hemi engine, which had arrived in 1964, was specially de-tuned with a new cam and lower compression (10.25:1) to make it better at low revs, but kept two four-barrel carbs. Chrysler's torsion bar front end was assisted by tubular shocks and an anti-roll bar. The brakes were heavy-duty drums, with 11-inch (279mm) front discs as options. The gearbox had its shift points altered to better suit the Hemi's power, but there was a manual available. Inside, the seats were thickly padded and the dash hinted of what could be achieved with its 150mph (241km/h) speedometer. The GTX was all about speed, because it could easily run the quarter-mile in 13 seconds (12 with racing tyres).
