but with a larger 3.75 in (95.25 mm) bore. It was used in the Ford Thunderbird, 1959-60 Edsel, Mercury, and some high-end Ford cars. The Ford version was the P-code "Thunderbird V8", which for cars equipped with a manual transmission had a compression ratio of 8.1:1 and was rated at 193 bhp (144 kW) at 4,400 rpm and with 280 lb·ft (380 Nm) at 2,600 rpm. Cars equipped with an automatic transmission had a slightly higher compression ratio of 8.5:1 with a quoted 198 bhp (148 kW) at 4,400 rpm and 286 lb·ft (388 Nm) at 2,500 rpm. The Mercury division had two versions of the 292 available in 1955. The standard engine had a 7.6:1 compression ratio and was rated at 188 bhp (140 kW) at 4,400 rpm, with 272 lb·ft (369 Nm) of torque at 2,500 rpm. The top of the range Montclair V8 came with a higher specification version that was rated 198 bhp (148 kW) at 4,400 rpm and 282 lb·ft (382 Nm) at 2,500 rpm. 1955 would be the only model year that Mercury would utilise the 292 in version of the Y-Block, with it being replaced by the larger 312 in engine for the 1956 model year. In 1956 Ford replaced the P-code 292 with a new 312 in³ "Thunderbird Special V8" version of the Y-Block, while the M-code 272 was replaced with a new M-Code specification of the 292. This M-code "Thunderbird V8" 292 was now optional on all Fords. The engine when fitted behind manual transmission vehicles had an 8.0:1 compression ratio and was rated at 200 bhp (149 kW) at 4,600 rpm and 285 lb·ft at 2,600 rpm, whilst the automatic featured an 8.4:1 compression ratio with a rating of 202 bhp (151 kW) at 4,600 rpm and 289 lb·ft (392 Nm) at 2,600 rpm. All Ford Y-Blocks were up on power for the 1957 model year. The 292 was available as the C-code engine option, once again with a slight difference between the manual transmission and "Fordomatic" automatic transmission. Compression was up to 9.1:1 in manual cars, which were rated 206 bhp (154 kW) at 4,500 rpm and 297 lb·ft (403 Nm) at 2,700 rpm. Automatic vehicles were rated 212 bhp (158 kW) at 4,500 rpm, torque and compression ratio are not listed in the Ford 1957 workshop manual as being any different from the manual car, which seems unlikely
