Late 50s and early 60s according to some quick googling. It looks like the trucks got the 292 starting in 1958 (the cars had it a few years earlier...in fact it was introduced in the Thunderbird). A truck in 1956 probably would have had a 272.
Thank you for that info. I actually had a 55 Ford car with a 272. I figured a 3/4 ton would probably have a larger engine but didn’t know the 292 came later in the pickups.
I think my 272 was only rated at 164 HP but that car really ran well. I remember beating a friend in a drag and he had 65 with a 352 and a four barrel. That little 272 would really go.
You’re correct. My Dad bought a 1956 F250 with the biggest V8 they had, and it was a 272.
The 239 OHV Y block would have been the big V8 in the F100 and F250 in ‘55. A 272 arrived in 56.
The 55 had a slightly curved windshield and the 56 was almost the same body style with a wrap around windshield. Some even had a wrap around rear glass and are quite desirable today.
Back them the big back windows were hard to sell because the interior got so hot.
