Are all PI car 4.6 the same long block (car vs truck)

Hello everyone.... First post here.


I was hoping that someone can shed some light to my understanding of Long blocks for my 2003 Ford F150 4.6L (8th digit "W" Romeo) with a 4R70W transmission

I was able to find a used 2002 F150 (Romeo) with over 300k and know that would work, but I was offered a 2007 4.6L from a Crown Victoria that has been rebuild by Ford in 1/8/2015

RM7S-808-XA
Part# 7W7Z-6006-BARM
Supplier:FOTEF

Will it work for my truck if I used intake, exhaust manifold, timing cover, flexplate, torque converter, valve cover,A/C, P/S, Alternator, wiring harness, ECM, starter. Will it bolt up and what issue will I get into.

Anything different regarding the newer block and head? It seems like it has the PI heads which should work on the truck intake?




Thanks in advance for any info!

Both those engines are PI, so your truck manifolds will work fine.

I would just note; you will.approach a Raptor(?) or Harley type, I would think. Better acceleration, but cams very ill suited for any engine lugging "truck" work. Less towing/hauling ability, except maybe for hauling a$&. Mayhaps the gurus could chime in.on this. As I understand it, truck cams lack valve timing overlap that cars, exp 'hotter' cars, tend to have. This lets exhaust gasses through for too great of extended times under heavy loads that a car suffers for only a few seconds, but a truck handles for even some minutes at times going up a grade, loaded,.or towing. So, maybe ideal if you are after a street rod chick-bait end result?
