You can't remove or install headers with the strap under the engine. I'f your going to install header with the K-member dropped, you're going to need to support the engine from the bottom with a jack of some sort. I used a block of wood to distribute the load along the base of the oil pan.
Even if the ratchet strap was on the engine mount bracket, you wouldn't have enough clearance to remove or install the header, the strap would still be in the way and right up against the header/manifold. Putting a bottle jack under the engine isn't as dangerous as you might think. As long as you aren't horsing the engine around while you bolt up the headers, you should be fine. There could be a way to rig it to where it doesn't impact the headers, but I didn't spend any time trying to figure it out.
I had removed the driver side header to be able to remove the timing cover which called for removing the oil filter/cooler adapter. I ended up swapping out the K-member after I had reinstalled the header and adapter. I ended up using the strap and the bottle jack.
I edited the pic that shows where it's attached. He's using the motor mount bracket to attach his ratchet strap.I was just trying to figure out if Tob used the manifolds/headers to hang the engine from with that MM brace or if there were other attachment points for using the MM brace and ratchet straps.
In his first post pictures, I see the MM brace and two ratchet straps and in his picture below that I don't see the straps around the engine, so I was wanting to verify exactly where he attached the ratchet straps to support the engine while removing the K-member?
Robert, you can support the engine by whatever means works best for you. I used straps because they fit the contours of the engine well without causing any damage. It really doesn't matter how you do it as long as it is secure.
