yeah....your right.. i was wrong. 93 is the full flat tappet elimination over roller as far as assembly.
92-93-94-95-96-97 fords have ridiculous continual running overlap and updates...explorers are the worst. wiring...heads...cams.. intakes and sensor packages ect...the dealer replacement engines, engines listed as 94 engines, could/did have the early truck cam which was not roller...these were oem warranty stock from places like dhamer p/t...and units which i handled personally is how i know....on a speed density truck it was not noticable...with a sefi truck you had to use the right firing order...whether maf or sd. not always easy to figure out either...
some of it is 49 state vs cali stuff...
though 94 can have different cams and efi systems. its sometimes a total cluster fuk .
only thing i know for 95 percent... post 94 is full roller for everything..except boat motors.
i have seen and pulled quite a few sets of 3 bar heads from vans. i dont know how or why they had gt 40 heads on them...they just did. i still have some of those heads...some were from maf equipped vehicles, some were not. they(several top dealer parts and building 1 research and advanced engineering) think it was simply production run explorer short blocks..when v8 explorers didnt exist yet.
hell....if what i was told is true...i seen a 35/28 hybrid axle in a explorer...the said it was bought new and never had the pig off of it. factory 410 gears as well....some people say ttb explorers never came with 4.10 gears. i have seen order charts that support it.
