Got this block cheap and upon disassemble saw this holethat goes through to the timing cover. Is this a crap block or can I still run it like that?

Check around the hole carefully for any cracks radiating out from it.
If it looks ok you can clean it up good and patch it with some JB Weld or other good epoxy.
It is not in an area that would jeopardize the strength of the block, so if there are no cracks it should be ok.

that hole is completely normal... all, and I repeat ALL 5.0l blocks have it.
I researched and they do have holes there, but they are usually closer to the bottom of the lifter valley and more oval or round. They probably serve to drain off excess oil from the lifter valley back into the pan.

There must have been some core slip issues with this block for the hole to be as high and shaped like it is.
Check the freeze plugs on the sides of the block and see how close to centered they are in the bosses cast for them.

Sorry, but it's been over 10 years since I put mine together and I just wasn't thinking properly with my first answer. The hole in that block is located higher than it should be and triangular shaped, so at a glance it appeared to be a broken spot in the block. :eek::

Well I'm probably gonna get rid of it anyway. It's a e7te truck motor non roller. Picked it up for 50 bucks so I guess on to the next one. Thanks though

You might maybe able to have it repaired at a machine shop for a reasonable fee.

You can convert a non roller block to a roller block really easy and cheap

.040 is a lot of bore for that block, it can lead to cooling issues. .030 generally where ppl stop.
I wouldn't want to use it for more then a stop gap until I found a block really worth building up. Just my opinion

.040 wont cause any problems, MANY people successfully run XXX E7TE blocks at .060 overbore.

and like I said, that hole is normal. Its left behind from the casting process and will not cause any issues.

It just doesn't look right. I have the stock 302 in my 87 I may use that but I liked the idea of building a 308. I have all winter so I'll be pulling the stock engine soon.

when you get the old engine out, make sure you take the intake off and check for that hole. It will be there, and then you will feel silly for wasting your time.

Knowledge through experience, and piece of mind are never a waste of time.

MANY do and MANY don't.

Once you get past the factory recommended overbore of .030 the strength and integrity of the block becomes suspect because it was never engineered or designed for larger than .030 overbores. My personal experience with a 302 block bored to .060 led to an ill running, constantly overheating waste of money.

If you are doing a high performance build, the block will be subjected to higher than normal cylinder pressures and stresses which the overbored block is even less likely to be able to handle. It just isn't worth taking a chance and risking your other engine parts on doing that when 5.0 blocks are relatively inexpensive and easy to find.

IF you are hell bent on doing it anyways, you should at least sonic test the block to ensure you have enough cylinder wall thickness to work with.

Rofl @ hell bent... for some reason I found this hilarious. could of used any other choice of words and would have fit your signature "serious, I WILL HELP YOU" attitude. No disrespect intended or implied, just found it funny.

At the guy with the original question, I would listen to mr. trojan. Hasnt failed with advice he's gave me.
