So..got back to the shop today and pulled the 2/6 bearings...I was concerned and when Adam showed up, he confirmed..they've got to be replaced..will do the full set...here's the pics:

Finally finished up on the bearings... Used the ball anvil gauge to check both the glyco's and the ones in the engine... Pics below are set up like the facing the engine from the front.. 1 passenger front..to 4 passenger rear... 5 drivers front...8 drivers rear.. (these measurements are in inches..or ten thou's)
I couldn't get consistent measurements on the bearings that came out..so I used plastigauge to check the clearance and consistently got 0.051mm..or a bit less..but it was pretty close to 0.051mm on every one, So that's how they will run
..

Passenger bank 1 bottom...(bottom bearing and then top bearing)..up to 4....

The business side of the bearings..no copper..but some galling..seems worst is the rear set (4 and 8)

remember the glycos got TIGHTER over time.....and you want to set the rod bearing on the looser end of the spectrum.... I will only run Porsche bearings......money well spent...and the new old stock ones are BETTER....

Interesting..I added the measurements I got from the glyco's together to give me a bearing thickness of 0.1175...
Now doing the same with the ones I pulled from the engine gave me these:
Here's the numbers.. and the difference from the glyco's
#5 - 0.1175 / 0
#6 -0 .1176 / 0.0001
#7 - 0.11765 / 0.00015
#8 -0 .1177 / 0.0002
#1 -0 .1177 / 0.0002
#2 - 0.1175 / 0
#3 - 0.1176 / 0.0001
#4 - 0.11755 / 0.00005
So...the Porsche bearings were thicker in almost every case...??? Like I mentioned above, the plastigauge came in at 0.051mm right in the middle of the factory spec of 0.03 to 0.069mm..so I'm happy with these..
Also, keep in mind, I'm a novice using the ball anvil micrometer...took me a long long long time to get consistent measurements ..so there probably is some variation...but plastigauge is plastigauge
, not too much user error there haha..

GB windage screen on.. Only had to "clearance" two of them as the rod nuts were just touching..a tug here..pull there..and good to go..you can see in the last pic how close..and that's just past the tightest spot
... Pan spacer and pan go on next week...and hopefully button it all up too.. ![Big Grin](https://rennlist.com/forums/images/smilies/biggrin.gif)

Yep, Greg's kit comes with a spacer for the oil pickup at the block and the two oil pickup mounts on the cradle.. as well as the spacer and longer studs/bolts for the pan. I didn't go for the full stud kit since this doesn't use any pan gasket..I ended up using loctite 574 or something like that..the orange colored stuff...
Adam (ATB) used this on his Simard spacer setup and it didn't leak at all.
Got back to it today for a short period of time and was able to the the cross member back in.. Going to take some work to get the heat shields in there..and the clutch line will need some moving around to get the bracket to fit near the headers too...
hope to have a roller next weekend.. we'll see..

She's all buttoned up....just waiting for the lightweight starter that is currently on my GT..will bring the GT to the shop next week, swap the starter out.. get it on there and then the track car will (should) roar to life...
hopefully our resident welding expert Al Blose will be available to box in our sway bar mounts and I can put on my Devek sway bar too...
.. Getting closer ![Big Grin](https://rennlist.com/forums/images/smilies/biggrin.gif)
We should definitely have a west coast 928 racer event...maybe we'll make you guys come up to the new track out in Shelton WA....the Ridge Motorsports park...I've heard it's a great track..

Got back to it this weekend. Found out my mini-starter won't fit (ebay special). Can't change the orientation of the starter so it still hit the pan. (anyone wanna buy a mini starter
) .. Al Blose came out to the shop also to box in my sway bar mounts (and Adam's too)...He did a great job (Thanks Al.... you rock)... here are the pics:
