The 4.0L Cologne engine is modular, the 3.8/3.9/4.2L Essex is pushrod. Basically, we have one cam in the center of the block, the 4.0L has one cam in each head.

rustangman, why is it you would recommend a tune before getting 4.10's? if it's for any reason other than speedometer correction, you'd have to try really hard to convince me of the point on a stock motor.
if you want to find out what gears you have, find a gear calculator online, there are plenty of them, and many are mustang specific so it will be able to tell you your transmission gearing
if you want an easy way to see if you have limited slip, raise up the back end of the car while it's in neutral and spin one of your tires. if both spin the same way, congrats, you have limited slip. if they spin opposite ways, it's an open diff.
to be quite frank, there is a lot of either bull**** or half witted information going on in here, some of it derived from profit motive
...i would think hard about anything you're told here. if you don't have much of a budget, then maybe you should just save up and make sure that what you're getting is going to be worth it and is what YOU really want, not a waste of money that someone else told you to get cause you didnt know any better

overhead cam does not mean it's modular, modular engines are called so because they have many interchangeable parts (the 4.6, 5.4, and 6.8 v10 are all modular motors).

EDIT: Nope, i was mistaken. The 4.0L cologne in the S197 is just an OHC derivative of the '90s/early 2000s pushrod cologne motors. My bad, Everyone please take note of what i just did, its OK to be wrong

Thank you for pointing out the obvious again, it's about time somebody stood up and started to point out these major issues with the forum.[sm=smiley32.gif]

You jumped the gun Juggy. I didnt say OHC was strictly modular, i just said the 4.0L Cologne engine was modular. Which I believe it is. I could be wrong, but i was under the impression ford stopped making non-modular engines when they stopped production of the Essex. There was an OHC 427 in the '60s. It was pretty sweet if you ask me.
EDIT: Nope, i was mistaken. The 4.0L cologne in the S197 is just an OHC derivative of the '90s/early 2000s pushrod cologne motors. My bad, Everyone please take note of what i just did, its OK to be wrong
