Anyone interested should look up yoyoparts.com, you'll see how many cars with a similar valve train have the exact same part. the manager at auto zone showed me this one. Cam in block = push rods. Overhead cam = no lifter/ no push rods.
However you'll find a hydraulic valve lash adjuster part numbers vary, but if you cross reference Elgin (HL7000) or Sealed Power (HT-2271) you might find others.
It's NOT a lifter!!! In my opinion it shouldn't even be hydraulic... It's really just a pivot point for the rocker. Not my idea. If you want more HP and more TQ with consistency just Google "4.7l solid lash adjuster" and you'll see what I'm using.

If it were not hydraulic, you would have to open the valve covers and make periodic adjustments for cam follower to valve clearance. I have to do this on my motorcycle with solid lash adjusters. It's not fun. Be thankful they are hydraulic.

So if i get this right, would you prefer to have hydraulic and non adjustable. You are used to the opposite end of the problem. If your bike were hydraulic and prone to catastrophic failure. The thought of a random lash adjuster sticking full open and the rocker arm falling off. No need to explain that.
I would rather keep an eye (or ear) on another component that will increase hp & tq that I can anticipate... Even if I have to go in occasionally and adjust. If they made that part so it wouldn't fail out of the blue I might not have ever needed to go in and tear it up.

I believe both solid and hydraulic lifters/lash adjusters have they're place. Lets not be a bunch of key board warriors here.......

The frequency of failure of a lash adjusters or lifters (they both work the same way and for the same purpose) is extremely low with modern technology. There are hundreds of millions of cars with hundreds of trillions of miles using this tech that have absolutely zero problems. Given engine / chassis packaging in not just the Mustang, but all types of vehicles, it would be an absolute nightmare if we didn't have this tech and they were all solid lifter engines. Worse, buying a used car or truck, would you be able to trust that this critical periodic maintenance was always performed on time (example, every 8K miles on my motorcycle) and correctly without dealer documentation? No, you wouldn't. Solid lifters have their place still in an extremely limited number of applications, but I'll take maintenance free hydraulic lifters every time, given the choice.

As far as working on a Mustang, give me a break...... https://mustangforums.com/forum/4-6l...e-rebuild.html

bump an 8yr old thread to argue the name of the lash adjusters in a mod motor

everyone go home, you're all drunk

This thread..... lash adjuster failure causing catastrophic damage in these motors is about the same chance of getting struck by lightening. Sure u might get a ticker but thays about it
