Just was detailing my Explorer's engine (03) and noticed that the intake manifold is different than it is on my Mustang.

Are they the same engine otherwise? Just curious.

I believe the blocks are relatively the same, while the mustang has a different intake manifold, exhaust manifold, and maybe some mounting brackets?

Other than that, I think it's also some tuning and messing with the cams.

isnt the explorers a pushrod? where ours is a ohc?

aaquib1992

I think it depends on the year. Some were OHV as I recall, while ours were in fact sohc. But I think they stopped using the OHVs in 01?

The 4.0L block is essentially the same, and are in fact interchangeable. Sure, the intake, front cover, mounts, etc. are different.

I thought so. Are all SOHC from 1997 to 2010 the same ? Or just certain years?

There were two 4.0's...a 160 hp and the sohc version introduced in 2000 which was 210 hp?

sohc came in 1997 i think.

They are the same block, but I believe just about everything else is different. My ex had a 2007 explorer with a 4.0 and I have a 2007 mustang with a 4.0 and the mustang has MUCH more power than the explorer. They are both OH cams, but the Intakes are visibly different

Gearing might be a bit more aggressive on the mustang, along with the OEM tuning. Probably why the stang feels faster. That, and the explorer must weight a lot more.
