Water pump and accessory brackets are on. Nearly ready to be dropped in.

Just need the clam shells and she’s going in.

The bolts I have for the clam shells show .514 of thread with the 4x4 brackets I believe this to be enough thread to us these bolts

It depends on the bolt grade and the base material that was tapped, sometimes you need 1.5x the diameter or more, and sometimes less than the diameter is sufficient (a nut is not as deep as the diameter for example). I actually have a calculator in my app that will calculate the min thread engagement so the threads are as strong as the bolt or better.

Don't count the tapered end as actual thread. Put a nut on there and see where it sits down too.

Are those 3/8"? 3/8" grade 8 bolts into 50 ksi cast iron would want .56", Grade 5 would be .45"

Just keep in mind, anything less than that, and it's likely you will strip the block out before you strip the bolt if it fails. That doesn't necessarily mean it will fail, it just calculates what will likely fail first.

Nice. That’s some good info right there. They appeared to be the stock bolts marked 3-6 so I am guessing they are grade 5.
 
I'm guessing the reason you haven't updated recently is because you've got the engine in and have been out driving your Jimmy? :)
 
I am guessing you have not followed the transmission saga. :doah:

I haven't!!! Bummer, I actually just read through this thread for the first time in its entirety last night and was hoping to see some updates about FNG getting his Jimmy back on the road...I'll go check out the transmission thread.
 
i would let this thread die and copy the link to this thread and insert it in your thread your using now .

but bent77 will tell the best option . :waytogo:
