4.6l aluminum blocks. What were they in
 

Ok so im looking at swapping a 4.6l SOHC into my 89 ranger 4X4. Ive never really been around these motors, my dad has a V10 and my friend is pretty comfortable with them but anyhow. Ive heard that some of them where aluminum blocks and some where cast iron. What years and models would have the aluminum ones as that would save me wait. Also i hear that the design of the heads was better after like 2000 so would i want to get one of those. Over all just looking for what year and models would have the best motor for me. Also im planning on finding a 5 speed and a manual transfercase to go with this if that makes a difference on the wiring.

Um Marco? Anybody have any info

these blocks came in lincoln mk8s from 93-98 and cobra mustangs and merc marauders. the first ones were made by a co. overseas called teksid they also make blocks for ferrari. these blocks are sturdy up to 1500 yes 1500 horsepower. in 01 ford changed the design to lighter by80 lbs and extra ribbing in the weaker places. these are known as wap blocks manufactured in the winsdor aluminum plant. go out and pick you up a book called 4.6 liter ford engines , by sean highland. i have a 62 unibody shortbed that i put this engine in.(from a 95 lincoln mk8 and this book has been very valuable.:-wink

ok thanks for the info. do you have any pics of your install. and i will look into that book

I have a 2002 F-150 with the 4.6. It has an aluminum block and head. I think the 2003 4.6's also had an aluminum block. I think Ford determined the aluminum blocks were too expensive and went back to the iron block in 2004 or 2005. My wife's 2005 Explorer has a 4.6 with an iron block.

My 05 Mustang GT had the 3v 4.6 aluminum block. Massive looking eng for 4.6 L. Traded for an 07 Edge

so i might be able to find an f150 with one it then.

The Teksid blocks are THE block to have and they were never in F150's. They are a DOHC engine and you were asking about SOHC. I am not entirely sure there was an all aluminum 2V 4.6L. The 3V's in the Mustangs are all aluminum though.

well the main reason i was thinking the sohc was that they would be a little narrower so make the swap easier but i have seen the dohc done. and now i am even contemplating a 5.4

Will the Mustang alluminum engines mate up to the F150 transmissions?

Or, will the new 3 valve 4.6L truck heads work on a '06 4.6L truck engine?

i have no i deal but i think the transmissions will cross so im thinking of either getting a complete f150 for parts or find an aluminum motor and then get the trans and transfer case out of a f150

...the 3 valve heads seem to make a heck of an improvement

The '01-'04 Explorers were aluminum block engines. There were actually a few Expeditions that ended up with them too. I drove a rental '04 Expedition at one time with 12K miles on it that had an aluminum block.

ok this is starting to get interesting now. right now my plan is to find a 4.6l 3v aluminum block and then get the 5speed manual out of an f150 and then try to wire the thing. keep the info coming tho.

Why not use the 5speed out of the stang? They are behind more power than the truck tranny's. There are also the 6speed tremecs that the Shelby's and the new '11 stangs will have.

Forgot about the 4.6L exploders, the Expedition thing is interesting, wonder if they just needed to get rid of some excess engines and dumped them into the Expy's?
