Happy day! Moving under it's own power.

So you drove it sitting on the floor?

Have you thought about putting the logo on the shifter knob?

Hey, Denpo! I have been away for a while and thought I would check in on you guys. Looks like you are making great progress.
I think I may be done driving for the winter here in iowa and will start my winter upgrades soon. They are minor compared to what you are doing.
keep up the good work.
Brent

First of all, sorry everyone who replied to my post, for some reason I didn't receive notifications about those, thanks for for the kind words.
Alas the project went into another speed bump.
Yes I managed to drive it sitting on the floor only to have the engine running very rough. After a tiny round trip limping around the neighborhood I went on to check the engine. Bad news: metal shreds in the driver side head, look like a spring damper broke, even if I couldn't find the culprint yet.
I order a compressor to spark plug adapter and try to remove the springs with the head on, but the retainers seem stuck, no way I could remove the spring without removing the head.
While I have the valve cover off I could see that the part list I've been provided when buying the car is probably mostly BS.
At least springs and lifter arms are not what the seller told me they were.
All that kind of discouraged me to fight for a proper 2017 run and went on to home remodeling/fixing projects that had been waiting for way too long according to SO. There is also this 3D printer that's waiting to be assembled.

With that 5.3 L33 sitting in the garage I don't really see the point pouring more money in the failed SBC.
So the plan for now it having it running next year with the LS engine.
And since the floorpan is still a bit too high for my 6"6' I'm looking forward to install sidepipe to clear the underside and lower the driver seat.

No I didn't think about that, but that's a good idea, will think about that.

Hello fellow vetteheads. It's been a long time since I've last updated.
Last year's work on the Corvette ended up with an engine failure at the first try.
Turns out I'm probably the one to blame since it appears valves' lash were totally out of wack, to the point the rockers were floating at some point during the cycle. The engine ran at most 4 time during the 8 years of the restoration process, only a couple minutes at a time and yet it seems it was enough to get the lash completely off. Could it be it's a flat tappet engine, you tell me.
So yeah, it pretty much ruined engine right from the start.
Well, maybe no ruined, but it would take to have the engine apart to really tell.
The amount of work to investigate is pretty much equal of an engine removal, so, since I have this 5.3 LS I assembled the year before I decided I'd go straight for the LS conversion that was I end goal.
If all goes well I could inspect clean and fix the SBC later for resell or whatnot.
So here I am with a fresh new plan and energy. Morale was low after the engine when kaboom, but I got over it, took time to work on other non Vette related task that were taking dust in my todo list and now I have needed time (and probably $$$) to make it happen.

This LS engine started with the purchase of an L33 shortblock on the LSTech classified, got it for 700$, I think this was a fair price.
From there I purchased from many sources (ebay, forums, kijiji, scrapyard) the missing parts at the best deal.
Basically what I got now it a 5.3 LS6 engine:

Flat top stock pistons.
used 799 heads ported in-house.
used LS6 stock cam, pushrods, rollers.
new LS6 valve springs.
Double roller timing chain.
Later LS6 valve cover.
Batwing oil pan.
Truck harness I rewired for car use.
Truck cable actuated throttle body.
Truck MAF.

At the time I had the engine put together (but not assembled), just to make sure the big LEGO was completed.
Now it's time to disassemble every again, take the shortblock appart and inspect everything.

Cylinder walls (1 to 8):












While cylinder wall seem to still sport the honing pattern, you can clearly see cylinder #3 has seen better days.
Scores can catch a finger nail and match small score on the piston between the top and the compression ring.

Is it doomed for reboring or should it be ok to use as is?

Main bearing: (top and bottom, 1 to 5)












I'm no expert in mail bearing, I just found that bottom bearing looks nicer than top bearing, but that's all. I'd love you guys tell me what you think of those.

Since I'm right at the start, if you guys got suggestion on what I should upgrade/replace, I'm listening with both ears.

Thanks for reading me.

I did a little 'resurfacing' of the block. A thick piece of glass and some sanding paper can do wonder.





The horizontal line is a camera artefact, because the surface was too shiny.











I went 120 - 320 - 600 - 1200 grit on them.

I also received my bearing removal tool, so now the block is absolutely bare, reading to get bored and cleaned.


All my orders should be delivered at my border PO box by tuesday. Maybe I can get it bored before next weekend. *finger crossed*
