Saw that today, I don't think it's an actual clevo block. It's got serious cubes on board, I reckon it's a 4.185 bore, 4.25 or something stroke, that block looked like alloy too but didn't see much. Could be an Arrow?

Okay so I ended up with 30-thou ring end gaps due to pre-gapped rings but what the hell, thats way better than the 120+ I had to start with, and with 11:1, worked heads, camshaft and possible nitrous use thats probably not a bad place to be. 
 
The whole shortblock is together and torqued to spec with new bearings and oil pump, the sump/timing set/water pump go on next and then I'll chuck it back in the truck before I put heads on it.

Yep, it liked the starter but it most certainly ran. Probably why it sounded badass - absolutely zero compression. I imagine it would've topped out about 70kmh with those ring end gaps haha. If I have 20 thou gaps this time around I'll be happy, should be about right.
 
Yup, generous piston to bore clearance but honestly I'm more worried about getting this thing on the road as soon as I can. My next lot of leave is in April (I generally keep working over the holiday period) and I'd love it on the road before then.
 
I'm using a very basic dial-bore gauge I got from ebay for about $40. It's consistent at least, although was a prick to set up. The micrometer is a metal bodied digital unit from repco and works fairly well. 

You're saying, it had 125 thou ring gaps? 😮
It actually ran like that!
 
And I thought my F-truck ring gaps were bad at 45thou, against a 20thou stock service limit.
 
Cleveland's are amazing...
I prefer soft cast rings, (which preserve the bore's), any day of the week!
 
So 3-6thou piston to cylinder wall gaps? (half that, over the circumference)
 
What mic's and dial bore gauge, do you have?
I've got a set of Mitutoyo 103 series mics, and I'm looking at their bore gauge options, atm.
Spoke to their local rep, the other week.
 

The sump and valley are post-cleaning session. They were caked in a 1/4 inch of black buildup. The bores were pretty good, though, as are all the bearings and lifter bores.
 
Sludge from age and lack of oil changes, coupled with only the occasional fire-up is my guess.

Getting somewhere. There was so much freakin' sludge in this thing. Luckily a small stainless brush, an old chisel, a few cans of degreaser and a whole lotta elbow grease got it sorted.

The block is clean enough and the bores measure up well at 4.001" to 4.002", but the stock rings are shot and a few of them cracked in half on removing the pistons. I measured two end gaps and they were both about 1/8" hahaha. 

The pistons themselves don't look as bad as I thought though. They measure 3.996 to 3.998 across the thrust faces so I'll probably reuse them. They don't show any signs of damage beyond some mild pitting - with that and the broken rings I'm thinking detonation.

The sump cleaned up well, too, after pouring about a pint of sludge out of it. The stuff had the consistency of cold porridge. Lovely. On the upside it looks like a good strong pan with true sealing surfaces, and even the dent in the lower section beat out just fine.

By the look of the thermostat it probably hasnt run in over a decade until I got it. This thing is crusty.
 
I can't see evidence of it being on gas, I'd say its just been plunked in there, beers were had, things were smoked and then the project got abandoned right around the time Port Arthur was happening.
 
Lots of cleaning ahead for sure. The timing set that came out was actually pretty tight, the picture doesn't do it justice. In all honestly I'm tempted to clean it up and see if it can be reused, or at least kept as a spare.

In the meantime, the block is out of the truck. Hazzah!

Got my bros EF 5.0lt & BTR off him, I'll have a think on plans for it & what to put it in, probably have my built C4 auto behind it,

Cover whire wheeled, camshaft and timing set out. 
 
This thing definitely had love in the distant past - the camshaft is a Crane grind (230@50 / 530 lift) and all the cam bearings are mint. The head gaskets came off dead flat and looking like they're out of a packet. The more I strip stuff off this the better it gets. Figners crossed for the crank and rods.
 
Ah yeah, I got the heads back as well. Hot tanked, acid bathed, hardened seats all round with a mild throat cut plus a valve job, new seals & mild performance springs. Nice.
 

 

 
 

It was previously on gas, right? Maybe the owner didn't bother changing the oil because it stays visibly clean for a very long time?

Double roller chain set, too. Had some love in the past.  Didn't spend too much on oil changes though. ! Or T'stat is waaay too cold.
