ok so heres what I got so far.

I plastigauged my mains and got,

1.  .0017
2.  .0017
3.  .0017
4.  .0017
5.  .0018

service limit on them is .0025 so im good........kinda
bearings have some scoring in them like it ran a hunk of shit through the oil and scored them, but the crank is mint so im gonna order a new set.

Ive only been able to plastigauge rods # 2, 4, 6, and 8 and they are

2.  .0016
4.  .0017
6.  .0015
8.  .0016

Ninja edit.....
1.  .0015
3.  .0017
5.  .0017
7.  .0017
service limit on them is .003 so im good there, and they look pretty minty. so im gonna run them. Gonna check 1, 3, 5 and 7 for shits and giggles


SO at the end of the day, I think im gonna order main bearings, and maybe some rings. Still on the fence with the rings.

those are
top ring .030-.035
2nd ring .039-.043

service limit on those are suppose to be top ring is .023 and 2nd ring limit is .033

so im about .010 over on both those but im thinking im just gonna say fuck it and run them. 

[ratcityrex]

Oh and pics

.0017ish. Close enough for me.


Scoring have 3 that link like that and 2 that look good.


Minty crank

[dvst8r]

Your plan sounds good. Leave the rings, better to be a touch loose than butted and broken.

[ratcityrex]

Loose and sloppy she will be then.

[turbohf]

i vote:  hone, clean, and reassemble with MLS/studs.


that shit as been in the mains im sure for 30k, it will still be like that in 30more after you toss a rod...

[ratcityrex]

Idk man, I'm sure it would probably be fine, but for $30 why not replace them.

This.

[ratcityrex]

Well sold the ss trunk trim and made $300  today. Welded in my subframe connectors tonight. In rhmt fashion I flux cored that shit.

[ratcityrex]

And here is some flux core madness. Laying on your back under a car welding above your head in a garage that's 88° @ 9 pm at night is not my idea of fun. And on top of that it kept trying to catch the undercoating on fire. So I would weld for 10 seconds and then put the fire out and then do it all over again.

Welding next to the fuel line was kinda sketchy

[crxvtec91]

Looking good! Leave the motor as is. Ring gap is just fine!

[Ntrain2k]

Might have missed it, but did you level the car up before welding them in?

Not talking about on the suspension, the actual car itself.

[ratcityrex]

I did pull out the tape measure and the car was 1/16 of a inch different from front to back. So I just left it like that. Pretty sure the tolerances from gm in 1966 weren't even that close.

Measured from a level floor?

If so good!

Yes sir. From the smooth hot concrete in my garage.

And main bearings for the nova ordered. $29.67 shipped. got to love rock auto.

[ratcityrex]

Well tracking shows that my main bearings will be here friday. Gonna Try and get everything clean up and ready for final assembly. Also ordered some arp ultra molly lube for all my main bolts, rod bolts and head studs. It will be here tomorrow.

[ratcityrex]

Ok so I got my new bearings, and some arp bolt lube. Shit works well.


Got them installed and plastigauged.

Came out like (I like to write the results of all my measurements right on the parts so I don't loose a piece of paper with everything written down)


1.    .0016
2.    .0014
3.    .0013
4.    .0016
5.    .0016
And thrust play is .003
Everything is Just a hair tighter than b4 but the bearings are mint. So I re cleaned everything after I checked everything and installed the crank with some assembly lube and now that's all done.

Hope to have the pistons all cleaned by Monday and installed.

[turbohf]

sweet.... moar! 

[trevor72]

sweet.... moar! 

Agreed.  Looking good, this thread was a good read/skim looking at pics.

[ratcityrex]

Ok so I have the whole bottom end together. Plastigauged 1, 3, 5 and 7 also since I didn't have the numbers b4.

1.  .0015
2.  .0016
3.  .0017
4.  .0017
5.  .0017
6.  .0015
7.  .0017
8.  .0016

So all is good there and here is the pics.







So next steps are to paint block, install cam/chain/gear, inspect oil pump and then install or order new, paint install covers.

Hope to have all that done by next weekend.

[crxvtec91]

Looking good!

[ratcityrex]

I haven't had a whole lot of time to do much work. But I did manage to get the block painted, cam and chain cleaned and installed, oil pump pulled apart and checked, looked good so I cleaned it up and installed it. Cleaned, lubed and installed the lifters in 2, 4, 6 & 8. Son just woke up from his nap so out of rebuild mode and into dad mode.




I have some money burning a hole in my pocket. I need to order up a megasquirt. So if any of your bitches know of anyone selling one let me know.

[danz]

Considered VEMS?  Almost as cheap as MS and seems to be way better.  I know it does 6 cyls not sure about 8.

I haven't even looked into it. Never heard of it. Looks like I'll be Googleing it....

[ratcityrex]

Ok, so I looked at vems. That shit is spendy. Starting at $700. And that doesn't include everything I need.

[Minor Threat]

Microsquirt will work with that trigger and is cheap as fuck.

[crxvtec91]

Hp tuners and a factory shorten harness?

[ratcityrex]

Hp cost to much. I can get a ms2 with everything I need for like $370 and it's fairly easy to use with all the other denmah files out there. If I was to use a stock ecu with a editor I would go with efilive.



And I thought about doing hp/efilive and having it tuned, problem is cost, and even if ross was to tune it he's 80 miles from me and I'm not about to tow it that far for the first fire up and try to fix all the small shit that might be wrong and waste his time while I chase down shit like oil leaks or what ever it may be.

Pay Ross in coffee or what ever to come to you.
