I just picked up a long block and need to put it on my engine stand. However, I dont have any of the bell housing bolts. Does any know know the size/thread/pitch so I could go pick something up from the hardware store?

I think those are M12x1.75. If your engine stand is anything like mine you can't use the bell housing bolts as they aren't long enough. I found bolts of the proper size at my neighborhood NAPA store.The car makes it possible, but the driver makes it happen.

Crap, another good question I can't 100% remember the answer to.
Someone has to know
I think it's 12X1.75 and 10X1.5I'm Not Right in the Head | Random Rants and other Nonsense1st Order Logic Failure: Association fallacy, this type of fallacy can be expressed as (∃x ∈ S : φ(x)) → (∀x ∈ S : φ(x)), meaning "if there exists any x in the set S so that a property φ is true for x, then for all x in S the property φ must be true".Comment

M12 is what you want. The head type/size doesn't matter. You'll be able to eyeball the correct length. They are M12's.
Here's a nice little chart with the US/Metric bolt size comparison.
Remember, for M bolts, it is referring to the shank size, not the head of the bolt size. So an M12 bolt does not take a 12mm socket. It's generally more like a 17mm? or there abouts.Last edited by Hallen; 04-18-2009, 10:33 AM.1987 E30 325is

thanks for the help. and realoem is a good idea.
I got some ~2in m12 bolts and they are working great.
but then i tore the head off and found 2 valves had some fun with the #3 cylinder:(
so the block and head are worthless... awesome.Attached FilesComment

That looks like the piston probably melted, and the heat/pressure took the valves with it.
Was it used in a forced induction application?

Damn
that is crazy, I just cant get mine to reev over 1200 so I picked up another M20 and tranny and E block to build a stroker and have a spare motor so I am in the process of cleaning the blocks and prepping everything. Muppet again thanks for the info man I appreciate it.

you could reuse the block, even if it meant a sleeve, but Its probably not worth it $$$$ wise when you can pickup another one so cheap over there.Just a little project im working on
