The GTO That Time Forgot! 1973 Pontiac GTO Colonnade
1973 LeMans GTO was more of a throwback to its early muscle car beginnings in the sense that it was a modest performance overlay to a basic LeMans coupe (D37) or LeMans sport coupe (F37). Although the once-feared 250-hp 455ci was still available in the GTO for 1973, it only had 544 takers. The rest were equipped with the 230-hp RPO-L78 4bbl 400ci V-8. Gear ratios were either 3.08:1, 3.23:1, or 3.42:1 (Safe-T-Track limited-slip optional) in a comparatively stout 8.5-inch 10-bolt rear. Transmission choices were a standard three-speed manual Muncie, optional Turbo 400 automatic (as seen in this example), or the rare four-speed Muncie manual box.
