First off, Spanish won't do you any good, Brazilians speak Portugese! I don't know what they are using under the hood of those things now, but Brazilian medium duty F trucks had 292 Y-Blocks in them until the mid-70's! Ford of Brazil did redesign the cylinder heads on their 292's, came up with something similar to a Windsor head. Brazil is full of surprises, they also built the '67-'72 F-100's until the 80's. But, before you try to go down there and collect one, they used the Pinto 2.3L OHC 4 cylinder under the hood. Guess they have a lot of time to get where they are going in Rio.......
