How Stroked is It ?

I'm looking at gluing together a 4 cam engine for my odd-ball ride.

After plowing thru the Lexus / Toyota 1 / 2 / 3 UZ FE Tech
for the past two months - I got a couple of less than stellar questions

Take a '98 Lincoln 4.6 Alloy cyl. block: which I'm guesstimating is 'THE BEST CHOICE' - > Is this a 6 bolt main?

Anyone with some great .jpgs of a 'nakid' block 'n mains for the 4.6 and Navi 5.4 ?

Any idea why for the 'blown' Cobra engine / 2007 - FORD chose to use a cast iron block ? and is that one a 4 bolt or 6 bolt ?

I haven't seen anyone on this site saying anything beyond one person using a Navigator intake on a project, about stuffing a 5.4 into they 'Linc' .......this
due to the intake height ?

checking this site for dimensions / weights

5.4 Navigator / 660 lbs. - cast iron block - forged crank
4.6 Aviator / 672 lbs. - Alloy block - cast crank

Is it weird that an Iron Block / Forged .5"+ stroker crank is 12 lbs less ?

It's ...the 'Dog' - am I right ?

Dimensions are 45" x 37" x 37" for both engines - so, same width for
a 5.4 with near half inch bigger arm ?

Has anyone stuffed a 5.4 crank into a 4.6 Lincoln block

- or can't it be ?

Has anyone transplanted a 5.4 4cam top end onto a 4.6 Lincoln block
as it might flow more air ?

Recommendations on Forums / Sites to research Lincoln / FORD 'build tech' on / at ?

thanks in Advance !

The 5.4 has a taller deck height. If you've got the room, there's not too many reasons not to go with a 5.4 4v, displacement is good..

Ford also used an iron block in the 03-04 4v Cobras (07 are 3v. I would have to assume for strength over the existing aluminum block at that time - however all aluminum blocks are not the same. The Mark VIIIs have a Teksid block which has been successfully run at 1xxxRWHP..
