Moving on!

Getting the pistons separated from the rods. Looks good so far.



Question; reuse the rods or get new?

Depends on the condition of the rods. Need to have them checked by the machine shop.

I'd say some of those pistons might be a bit low on compression.

Bad news. Machine shop called and says the block is unusable. Lots of cracks with some going into the bores...

Pretty disappointed

Sharp: That's just what happened to me, I suspect it must be the usual run of things from what I've read. But there are good blocks out there, I know because I found 4 of em. Start asking car guys wherever you see them.

I did. Got some new tools, learned a thing or two. I really felt I was making progress towards the hot rod Iíve always wanted, but will just need to find something else.

I think Iíll clean up / refurb the parts as best I can then sell them off, then track down another project

Got everything back


Definitely some bad cracks


But they cleaned everything else up real nice which is great. Will probably part it all out and sell it to fund the next project.





Thanks all for your help. I had a good time.

The block will make a good mockup tool while you look for a usable one.

Sharp, how did your machine shop locate the cracks? From your pictures, it's a little hard to see. Since they didn't hot tank or shake and bake it.....might not have worth the expense.....I'm curious how they were able to tell if the cracks were unrepairable.


Probably a stupid question, but consider the source!!

I agree. I see some rust damage (that is easily overcome), but no fatal cracks (I do see a "Part Number" crack, but they are no problem.) Perhaps a few more pictures of the actual areas of damage would help. Don't give up so easily.

I;d want a second opinion on the cracks. There are some new stop leaks, like Morso's ceramic. I heard of some ne stuff, can't remember the name you can leave in the coolant,

They didnít photograph well but there was one in a port that was unrepairable and another that went from a port straight into the adjacent bore. And a bunch more besides

It was done by mag particle.
