what is the difference in the 5.0's

[dieseldane]

really? why is that?


i sure as fawk am not guessing. built many and its common available knowledge from the mamufacturer.


like i said...theres crossover era....and maf/sd as well.

Who knows, something that was stuck in my noggin for some reason. I'm pretty thick headed, when something manages to get in somehow, it's just as tough to push back out.

94 is a crossover year.....if it was 95 it would have a roller. 302 or 351.

And you're wrong on the 302's. 92 was the first year the trucks and vans went roller. 94 the 351's went roller with the F4TE roller block. The 92-93 trucks got the "base" roller cam used in the Vic's/towncar/Marquis. 94 they got the F4TE roller cam.

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.

I've run across production run substitutions too. I learned to never say never when it comes to this. I replaced a friend's 302 in his 92 van, it was a roller motor with the Vic cam. Also seen E6 heads on vans and pickups while most had E7's. On 351's too. Also seen a mix of SD and M/A on 94 pickups. Back in the 80's I pulled a 428 out of a 60's Merc Marquis that was the original engine, topped with a 410 4V air cleaner. And pulled a 410 out of my 70 F100. Didn't just have the pistons but the crank to match. Another little known jewel is the D8VE-A3A 302 block. It had the big Hi-Po main caps like the Mex and the 289 Hi-Po blocks had. And then there's the Mex block myth about it being heavier. It wasn't. It weighed the same as the rest of the 70's blocks...…...136 lbs.
