Engine Stand with a Straight 6

[Willfin]

I have the bottom end of my tvr straight 6 on the engine stand, as shown below.

Question I have, are the 4 gearbox bellhousing bolt points strong enough to also hold the head?

I've got a concern that I may crack the block? About 250kg all in with head.

Settle my nerves please!

Applying force*distance I think you are taking a big chance there. I know just how crap the threads (and castings)are on these TVR engines having had to helicoil just about every hole on an AJP. I would not be inclined to add any more weight. Maybe a couple of planks and a jack across the legs of the stand to add a bit of support?

Yeah that was my thoughts too. I'll make a little wooden engine stand for the car end once I know I don't have to turn it over again.

Thanks

If you still wish to rotate the engine, obtain another engine stand (one on the bay now for £16, or new for £42) and bolt onto the front of the engine? - yes, welding / modding the base would be needed, but you could now rotate the engine.

I run a straight six, but a cast iron Triumph block.
Like you, despite the added strength of iron, it still weigh a lot, so I use an spare rear engine plate/gearbox adaptor.
Seven bolts attach that to the back of the block, so making the load on each nearly half that if I used the four stand bolts.
Which go into holes on the plate, which is only for this purpose, and made of steel, so no worries.
See the pic, of the block and plate on a winch - the four stand holes on the plate are obvious.

If a TVR engine doesn't have such a plate, then you could make up an adaptor from a sheet, drilling holes as required.
The Triumph block has a separate rear crank oil sea housing, so I enlarged the originally circular hole so that I could install the seal while the engine was still on the stand.

I just support the weight with a wood prop. Had an alloy block on a stand in my garage for years like that.
