Default K20a2 on an engine stand. What length of bolt?

I know that I need a 12/1.25 bolt, but what length? I'm thinking about 6" (150/160mm) so that it can fit through the tube for the engine stand and still thread into the block as well.

Am I missing something, is there another way I should be getting this motor on this stand?

Just swung by a specialty hardware store and got 4 12/1.25 x 120mm bolts... $21.20.

But, at least I'll have them now.

I ordered 12mmX1.25 threaded rod from McMastercarr and cut it to length.

Let me ask you a question then. Don't you need the bolt head to be snugged up against the "arms" of the engine stand?

I'm asking this becaue the bolts I got are about 3/4" too long and I'm concerned that they may fail or bend due to the amount of stress on them.

K;

If you use threaded rod, you can lightly screw them into the block until they bottom out. Then use a nut and washer on the other side of the engine stand bracket. That's as good as it gets because you are catching <U>all</U> of the threads in the block.

Damn...thinking ownz me.

Is the below what you got (basically)?

Part Number: 95245A110 $27.89 Each
ASTM Specification ASTM A193
Material Type Steel
Finish Plain
Grade/Class Grade B7
Type Fully Threaded Rods and Studs
Steel Type General Purpose Steel

I think I'll get 2 300mm and cut them in half. But damn, over $50 for these things.

I think I found a solution to my problem I just added a nice stack of washers to fill the gap on the stand side and the motor is finally sitting correctly. It's a little cheaper than buying all new bolts/rod.
