    Engine stand to engine bolt strength

    What do you guys use to hold your engines on engine stands?

    I'm thinking high tensile (i.e. 8.8 + ?) or is that overkill for this purpose?
    ?

    i use high tensile 8.8 to hold a toyota v12 to a supercheap auto engine stand. i did find that the washes supplied with the stand were too soft and bend easily so i would replace them.

    one of the wheels is sitting in the air but none of the bolts have broken.

    LOL. The brand of stand I am about to blood is a SCA item as well. So if 8.8 is good for a toyota V12 then an all alloy 5 pot should be fine I'm guessing. Thanks

    I think "cheese" bolts are OK but may only come in coarse thread, 4 8.8 bolts aren't going to break the bank, although i did avoid buying bolts that were fully threaded because they were shitloads more than the ones that weren't. ideally you would use the bellhousing bolts but it depends on geometry of the stand.

    Bell housing bolt up points will be used. I was considering more the length of time the thing might be hanging there and possibly getting leaned on to undo/tighten stuff on it.

    Not the actual engine but same block.

    Mine's got bolts that have been cut in half and welded back together with extensions to make them long enough.

    I've got Holden 6cyl head bolts holding a Clevo and a 250 crossflow on the engine stands at work. Use whatever you can find, the higher the grade the better though.

    I think last time I had an engine on a stand, I used sockets as "long washers" because the bolts were too long...

    I reckon a clevo with cast iron heads would be on the scale of heavy, near the top, I just used some black grade 8.8 fasteners random length with some big nuts as washers.

    Don't stress.

    Just be sure they engage as much thread as possible, especially in an alloy block.

    I was always more worried about the flex in the stand - used to have a prop under the balancer when rolling it cross country to keep it from fatigueing at the bottom joints...

    I welded nuts to some studs and rounded off the hex so they fitted inside the sleeve on the engine stand and used normal bell housing bolts into them. It looks as dodgy as it sounds.

    what kind of engine stand do you have the clevo on? we tried 2 different stands when attempting to do a rear main on the boat motor. even tried welding steel onto the second one to stiffen it and it was still creaking and groaning. we gave up and took it to the engine builder to deal with.

    Opened thread to say this. I used some 8mm round bar to extend the bolts in mine...
