Engine Stand Bolt Torque?
I assume that engine stand bolt torque should be about the same as transmission bell housing to engine torque. I have a turbo 400 going in behind a GMPP ZZ383. I could not find the torque value for the bell to ZZ block anywhere. Is 28 ft/lbs correct? Any info is appreciated!

The purpose of torquing a bolt is to prevent it from backing out due to vibration. Unless your going to run the engine on the stand why bother. If you are then 25 or 30 is fine, just bolt it up wrench tight.

Slightly related - what size bolts are you using?
I have a nice new short block en route, and my beat up third-hand engine stand doesn't have bolts. I'm worried about using the wrong thing and having the block fall off and break my foot...

Hi Carp,
Like you, I salvaged a stand head from the junk pile with no bolts and made up a base. The bolt length varies from stand to stand. I just threaded a 3/8-16 into my new block until it bottomed out, then marked and measured the depth, added this to the ear length of the stand and that got me pretty close to length needed. I added 1/4" to length just to make sure they were long enough and to allow for washers. Your main concern is bolt "Quality", do not settle for less than "Grade 8" strength on allof the engine stands bolts.
