Default small block to engine stand - bolt size ???

I am VERY CLOSE to buying the GM Crate 350 engine. I just purchased one of those 2000lb rotating engine stands... as I plan on dressing-up the engine before installation.

What bolt size & length do I need to mate the two to each other ?

The bolts size would be 3/8" but length depends on the engine stand.

2000 LB stand! What kind of motor are you planning on. My 750 lb one holds up fine. That would hold two BB chevys.

Bigger is better. I have the 1000lb version with the drip tray. My engine was on the stand for about a year and a half.

The block bell housing bolts are 3/8-16. Probably need 4.5"- gr 8 bolts. Be sure the bolt doesn't bottom out in some of the holes. The end holes are through holes,BTW.

Is that a geared head stand?

great !

When I looked over the selections, only the 2000 lb stand had big-nice-hard wheels.

I haven't unboxed it yet, I can exchange it for a 1000lb stand. The motor will eventually be complete - carb, starter... Would that one (1000) be sufficient ?

You might want to wait until you get the stand to see what size you'll need. You may also need some large washers as well.

I agree on waiting until you have the stand you're going to use to buy the bolts.
I like the 3 legged stand, although they can topple over if you're not careful. The 25 year old 3 leg stand I have is great for SB,TH400's, and differentials. It's taller then the U shaped stand I have and made better. Of course the 3 leg stand was made here in the USA where as the U stand is your cheapo import. It's something I leave a rear end on but don't like it for an engine. The better quality stands are worth the money.

OK, I took the $90 2000 lb stand back to Harbor Freight, and opted for the 1000 lb model. I realize that probably the 1000 lb model may be an overkill, but to my surprise it just went on sale today for $40 !!!!

So I got a big chunk of change back.

Thanks for all your help.

Now, please keep your fingers crossed for me - that the GM Crate Engine deal doesn't fall through...

Yeah, the 1000lb will be enough. A complete all iron SB weighs about 550-600lb, an all iron bb weighs about 650-700lb.
