I assume you still have to hone these cylinders to smooth out the pits and get rid of the higher chunks?
HAHA
no that’s just a poor photo there is no marks or anything just light crosshatching.
the cylinders are perfectly honed and clean to .003 over the piston size. Coulda went a little tighter but plan to do a lot of track days so it should be good.
Ok getting some progress.
I got my crankcase carrier align honed with my ARP bolts and measured by superior automotive and now it’s dialed. They are a great shop with chassis and engine dynos super flow machines for flowing heads etc. Every tool you can imagine, if your in SoCal they can definately take care of your needs lots of older experienced guys.
Today I installed my IMS bearing I also had the IMS gears pinned so now the IMS shaft is ready to be installed in the carrier looking forward to doing that tonight.
BTW the original IMS bearing had a 135k on it and it felt completely smooth.
Really enjoying this rebuild thread. I agree about Superior, some time ago they did a full align hone/machine work on my 454 (block/heads/intake) when I rebuilt a C3, old school talent that's sadly missing in a lot of places these days. An old school speed shop in Lawndale was how I got introduced, I think that's now gone too.
Yeah went with the EPS bearing. Nice kit comes with installation tool and oil feed if you choose to use it. Has a beefier center stud then stock as well.
Great thread, looking forward to the results. It would be really nice to have a lower cost option for those with bore scoring but can't afford or justify the Cadillac rebuild. Very interested in reliability so please keep updates on this thread once she's back on the road.
Just noticed that next to Baz Hart's posts (which are always informative) it now says "BANNED". WTF?

No idea why Baz got banned if that’s the case.
I wanted to do this build the way I felt like doing with all the info involved. I’ve built a bunch of different engines, motor cycles , chevys fords Mercedes mechanical FI, Austin mini Cooper. And I work at a power plant we’re we overhaul big 25’ long engines. So I feel comfortable building it. So far it’s not to hard with the info that’s available from Jake Raby and other videos out there, I do have the Porsche repair manual as well.
I am in the camp that there is many ways to build it, in terms of parts. I wanted to do the steel sleeves and the new Mahle pistons. But the LN parts are proven and a good way to go to. I did purchase k1 rods from LN as they seem like a good upgrade at a reasonable price.
Alright I’m ready to move to the garage
this morning I attached the bank 2 rods to the crank and added the IMs hardware. Put together the bank 2 pistons and rods.
ready to move to the garage to get the carrier into the bank 1 crankcase half. Hoping to get that done and possibly install bank 1 pistons this afternoon.
The golf course is calling though to at least hit a bucket so I’ll see.
if my wife came home and found me in the house/kitchen rebuilding an engine...next to her Eames chair, I would have to disappear for a long time. roll scene ...
1. the flat six design has an inherent negative that on bank 2 the thrust side (the side the rod pushes against) is the top side. Bank 1 the thrust side is the bottom side. Which because of gravity should see plenty of oil.
2. As these engines get older if you lose oil pressure or overheat a little because coolant or oil is low. The bank 2 thrust side will see less heat and less oil.
Interesting thought, I'm not sure how much it matters.
A ton of oil gets thrown off the recip. As the engine gets older and pressure decreases, (so clearances larger) more oil would be tossed off the recip.
Gravity doesn't seem to matter on inline/vertical cylinder engines.
