It looks just great. I'll be looking at those other blocks tomorrow to see what they are and bring you a couple if they're worth it.

:eek: graemlins/thumbsup.gif

woah! good job mike!

the block looked even worst when i saw it there in person!

heh didnt know onovakind67 was the guy from fairfield! graemlins/waving.gif i was the one in the blue truck

Thanks guys but I can't take much credit,,,,, my wife just threw it in the dishwasher along with the dinner dishes with her secret super soap & when I got it back this is how it looked??,,,, :D :D

Yea, I'll have to admit It was a bit "ugly" :D
Kinda had my doubts when I first saw it.

Gotta love the shake-n-bake...

I need one done this weekend, if I can beat it apart...

Too bad your so far away.

Sheesh that was FUGLY!!!

What processes did you put it through to make it look so good?

Thermal cleaning & airless blasting with stainless steel shot & a lot of finish work in all the oil galleys etc by hand & now it's clean enough to get in the door for machining so it can be cleaned all over again after being wacked & whittled on ;)

BTW, these pics are before any machine work, just cleaning & trust me, this was not a 30 minute cleanup deal :D

Yea no kiddn there :eek:

Is it worth it for a customer to have all that done versus finding a different block?

Just seems like a lot to do before it can become useable.

Not really.

I kind of questioned this block because of the condition but it cleaned up better than expected.
My main concern was the bores as most that are this rusty are pitted & basicly usless to me.

It doesn't make any difference to me how the block starts out as this is how we clean almost all of them except for stuff we are freshening like race engines that are capable of being cleaned in the jet washers.

We only have one way of doing things be it machining or cleaning & if all someone is concerned with is the cheapest price in the area we tend to send them elsewhere :D

To be a little blunt,, I am not interested in doing half assed work & this goes for cleaning as well as machine work ;)

Basicly the same amount of time & work goes into all the blocks except on this one it was sand blasted before going in the shot cabinet so I didn't make a mess out of my stainless shot as it ain't real cheap.
Other than that, it's how we clean them smile.gif

Thats what I called a seasoned block :D

Make that "WELL SEASONED" :D

Man I've had blackened redfish that wasn't that seasoned. :D

What ocean was that thing dreadged out of?
How do you clean the surfaces of the cooling jackets around the cylinder walls. With that much rust and pitting, I can't imagine them conducting much heat away.

Oh, I love "naked engine porn"!!!!

It sure wasn't a virgin tho, from looking at the before pic's!!

He, He!!!

What is it, as in, anything special or unique?

I noticed the 4 bolt.

Seasoned? I would've said "screwed", but man, what a good job of cleaning her up! Nice work!!

WOW :eek: , That was BEFORE machine work?? I have a Mopar block that has been in the woods behind my house for about 15 years, doesn't really look any worse than that thing did..

I noticed the 4 bolt. It's a 3970010 010 020 standard bore casting from a late 60's Chevy truck. Nothing special but probably one of the best GM castings.

JR,
The Thermal cleaning & blasting really cleans the water jackets very well. It will still leave some crap behind but probably 90% of all the crud will be gone.

The biggest problem will be the condition of the bores themselves. If they are rust pitted very deep there is nothing you can do short of sleeving which isn't real practical except in the case of a very rare block as it ain't real cheap to sleeve 8 cylinders :D

Problem is you need to clean it to be able to tell if the bores are salvageable.

===============
Mike,
I could use your flywheel. I have your crank in the lathe wacking the counterweights down & it should be back on the balancer today or Monday smile.gif

My God! :eek: What do the bores in something like that clean up to???

In my experience if it has been sitting bare, and not water sitting on top of a piston, .030" will clean up a pretty nasty cylinder.

Rust can look really bad, but it grows outward more than it eats inward.

I had a 454 block, the first one I ever "shake-n'baked" for rust removal and I doubted it would clean up at .060" it looked so bad.

cleaned it, set it up, made a ~.026" cut and it cleaned up. Did all 8, stuck it in the hone, and it looked new.

As Mike stated even after a thorough cleaning, machining, re-cleaning, I take a block like that and run a brass wire cleaning brush for rifles on a drill through all the oil galleries, hone the lifter bores, tap all the threads, blow it off with air, jet-wash, the I usually also take to a car wash and pressure wash all orifices in the motor.

THEN it gets another rinse, blown off, painted, oiled, and assembled.

I spend a day after they leave the shop... just cleaning.

Hi Mike, The engine cleaned up nicely. Great pictures also. I got your "E" mails, just been too lazy to reply. After you machine this block please tell us how much you had to bore it to make it usable.

Hi Harold,
90% sure it will clean at .030.
If I can find time,,, & remember graemlins/clonk.gif
I'll try to post a couple of pics of it on the boring mill ;)

Hey Jake,
Missed your post,,, hell, it's only a short drive out here :D
Shouldn't take more than a,,,,day,,, or two,,,, or so graemlins/waving.gif

Mike,
If I came up we'd prolly spend 2 perfectly good work days BS'ing without getting anything done.

I found a place locally that does it. $30.

I have an excellent machinist I use but he's over 80 miles one way away from me he uses a vat.

Friend of mine bought a 420 SBC off Ebay and the block had been brazed around the top oil galley above the rear cam plug, and was leaking oil.

After lookign at it I told him to get another block, so I ended up finding him a block in a local wrecking yard. Shortblock laying upside down with a Th400 attached to the back. An ant nest built up between the bellhousing and block.

What a mess. Brought it home last Thursday and spent 5 hours honing, beating, torching, and waxing it apart.

I think it'll clean at .030 no problem.

Now to fill it, clearance it, bore it, deck it, and get it going again..

I think I spend most days not getting anything done :D

$30 to bake & blast,,, crap man,, the guy is almost paying you for the privilege of cleaning your block :D

The damn propane costs about half of that ;)

When I was an apprentice, the boss claimed that seasoned blocks were better, especially those that sat out in deep freeze winters. ???

Sure looks like a great, seasoned core!

Mike,
I took it to a somewhat large engine reman place locally to be cleaned. They must do several at a time because they said it would be Monday before it got cooked and Tuesday it would get shot, because they didn't have enough blocks to fill the basket.

The machine we used in a machine shop I helped at would only do one block or 4 heads. Just a rotisserie.

Then you hoisted the cage straight from the burner to the steel-a-brator.
Then again to the final machine to get ost of the beads out.

The 454 I had did make a mess of the beads smile.gif
They were rusty for the next couple of blocks, but eventually the rust gets vacuumed out.
