Differences in a 5.4 truck block and a 5.4 cobra block

[Late4Work]

Im trying to find out the differences in them, if u can crossbreed the two engines, is there a difference in stroke or anything like that???

There shouldn't be that I know of. A 5.4L is a 5.4L, now the block might different design as webing or casting but parts should all be matching.

the only mustangs from the factory with a 5.4 is the cobra R and the new GT-500. which are aluminum, the truck blocks are iron

I know the truck block is an SOHC 5.4 and the 99 up Navigator 5.4 is a DOHC making 300 horsies, making the Navigator engine more desireable.

I don't think either the Cobra R or the GT-500 use an aluminum block. As far as I know the only 5.4 aluminum block is in the Ford GT.

hank is correct. other than that the only thing that really separates them is the heads.

your right, both are cast-iron. the difference is only the heads then
