Those bearings look pretty damn good. Well if your pistons and rods look like, that mine are going to look like they were dipped in hot fudge. Ill post up some pics when their out. My local shop said it would be between $60 and $100 to hot tank my block and rotating assembly. Not sure if its going to get everything off but hopefully it will be good enough. Do you not have access to a local hot-tank, or do you just want to do it by hand?

I would get a quick ball hone on those cylinder walls, the trick is to get a nice movement up and down to get a good cross hatch.

When I did this I got the total seal ring set from summit racing for the 5.3 pistons and I was planning on a turbo build and was told by the guys over at total seal that they recommend between .020" gap and .022" for the first two rings. I did .021" for both. Sadly my cylinder walls were worse off and another unexpected purchase was made so I never got to finish.

looks good, looks like it is a 5.3, nicely done.

Alum has to go into a cold tank. A hot tank is for steel/iron etc only and will eat aluminum.
My engine builder friend doesn't have a cold tank. Too many govt regulations etc. I'm surprised they have let him keep the hot tank.

Just removed the cam from the block and when I did the #2 and #3 cam bearings came out with it lol (pulled it out slow and careful too). They are toast! DEEP grooves worn into the cam and the bearings, and the tips of two pushrods were damaged pretty bad as well. Not too worried about it as I'm replacing all this stuff anyways, I wonder what happened to this thing?

That doesn't sound too good to me. Do they look like they spun in the block? If so, the block may be toast.

Ooh, yeah, not good. Hopefully the block is OK.

Will be running a Gen 4 LY5 bottom end here $125.00 from EBay vendor, LS9 cam, Ported 243 heads, and considering one of the DNA GT45's...talk about budget.

What a deal, I got my entire long block (oil pan to intake/heads) for $200, hopefully it doesn't turn out to be a boat anchor haha. Heres a couple pics of the two spun bearings....those grooves are nasty!

Also...two pushrod tips were chewed up pretty bad. Im not sure if two lifters went bad or if that was due to the cam bearings going bad? It looked like someone put the prod tips on a grinder.

I think you will be ok. I'm going to guess they got hot and shrunk, it doesn't look like they spun in the block. back side looks ok.

Finished the clean up on mine, came out quite good.



When you get to the mains, mine look like this:

Man Im jealous! You could eat off that thing haha.

I was trying to figure out what the backside of a bearing would look like that has spun in the block looked like, but had no luck. Thanks for the intel.

What did you find most useful for the cleanup? I've been using some Lacquer thinner, which seems to be working well.

I started with Purple power cleaner, but don't let it dry....
Then paint thinner and brake cleaner, I bought a case.
Then laundry soap mixed with dish soap and hot water. Followed by pressure washing. Hand brushes, scotchbrie pads and a small wire brush.
Took me quite a few hours.
I got a bath too, and now smell like the above mentioned cleaners.
Good thing I'm single.

Maybe I'll throw some coals in the valley and put a grill on top.....

Sorry to tread on your post.

Mine after just a parts washer cabinet and some scrubbing with a nylon brush. Turned out great, just be sure to blow out everything with compressed air afterwards.

Sounds like a stout combo, Ill have to try some of that purple stuff.......tread on my friend, any info is helpful.

good idea on the brush, Ill have to put that on the shopping list.

That looks good Sarg. Wish I had a parts washer cabinet.
Did you remove the oil passage plugs? There was some sediment in behind the mains....I will still need to do that.

BTW...the car mine will go in:

I removed my plugs, didn't find any sediment there, nor any in the pick up tube screen which makes me happy. I started the clean up finally, hopefully it will come out looking as good as both of yours. Ill tell you this much...Evaporust works wonders! My water jackets were really bad (caked in rust), so I sealed the water pump inlet and filled up the water jackets with the stuff over night...amazing results! I plan on using it for my cylinder walls too, using a method I read online for soaking them. After that it will get a scrub down with the Dawn, then its off to the machine shop for inspection! If that goes well it'll be the hot-tank, a light hone (hopefully no bore required) and some new cam bearings while its there.

Yeah I no longer have access to the one I used on that block. Dealings gone bad and getting tools taken, just a bad scene so I got away from that place. I am sure a $100 hot tank could do the same or some good old fashioned elbow grease, but that sped things up a touch! I got a buddy who may be doing the same in his Nova if he can ever finish his rat rod truck, lol. I miss my '63 SS that I had years ago.

New question, I'm looking at a pair of worked stock heads ( Ported 862 Heads , with valve job 2.02/1.57 ferra valves milled .030 over to 58cc chambers) and wondering if I use these with my build, would I run into any PTV clearance issues? I'm planning on having Martin @ tick do a custom cam after heads are selected.
