This is what I found
"In the light pickup truck arena, the new R-110 pickup was a handsome little rig. The clean lines of the grille, hood and front fenders were simple, but pleasing. Exterior chrome plating was used only sparsely, on the identifying logos and on the door handles, but the design did not need chrome to look good. The 115 in wheelbase model featured a 6.5 foot pickup box, and cost $ 1,384.00. For 1954, IHC introduced the new R-100, which looked exactly as the R-110, but cost US$ 60 less, and carried some improvements. including a bit more horsepower, improved gear ratios, larger brakes, more flexible springs. With a 4,200 lbs GVW (4,600 lbs on R-102) riding a 115 in wheelbase, the power came from a Silver Diamond 220 cid (3.6L), in-line 6-cylinder engine with overhead valves, 104 hp and a 7:1 compression ratio (up from 100 hp and 6.5:1 on the R-110), driving a 3-speed transmission and a semi-floating rear axle. By mid '54 it could also be had with an overdrive transmission which provided a 30% reduction in engine speed at 60 miles per hour, or with a torque converter fully automatic transmission (basically a GM sourced 3-speed Hydramatic). Power steering also became an option. Tire size was 6.00x16 6 ply."
