    Are all 4.0 SOHC Block Castings The Same

    When Picking a 4.0 SOHC Block for a performance engine, is there a preferred block casting?

    I know the 4.0 OHV had several different block castings, but not sure about SOHC?

    As far as I know, the SOHC only had one casting. I've never heard of different years having an advantage over another.

    Thanks Zoom

    I couldn't find anything either! Just wondered if there might have been changes from the first year it was used in the explorer.

    I was looking into this also and came across the following article on the 4.0 that lists info about the different blocks, cranks, rods, pistons, cams, heads, etc...

    "Rebuilding The Ford 4.0L Pushrod V6, Doug Anderson, Automotive Rebuilder, April 2001". Here's the link...

    http://www.babcox.com/editorial/ar/ar40123.htm

    While this article mostly relates to the OHV pushrod engine, it does mention the SOHC engine a couple times.

    I'll correct you!

    No they aren't!

    Very similar though!

    This might be worth reading through:

    I would think the article would mention different blocks for different years if that were the case...

    Thanks for linking that Rockledge, there's a lot of good tech info in it that I wasn't aware of. Not sure I like some of the weak areas they pointed out, but it's good to be aware of them.
