Re: Secondchance - 380 build begins!
 

There is a slight difference in the fabrication of the King thrust bearing, compared to the OEM thrust bearing. The OEM thrust bearing flanges are spot/tack welded to the bearing shell and does not have any fillet on the back side. The King thrust bearing is formed from one piece and has a very small fillet which interferes with the bearing surface in the block (both upper & lower crankcases), resulting in the bearing not being completely seated. The result is a tight bearing that doesn't allow the crank to turn freely. The solution is to simply grind a slight chamfer (abt 1/32") on the outside edges of the bearing surface if the block so that the bearing shell will fit completely into the main bores.

When we ship a set of King Main Bearing to a customer, a detailed instruction sheet is included which describes the modification required.

Personally, I think the King Main Thrust Bearing is better than the OEM. I have seen a few of the OEM bearing that the thrust flange welds have cracked/broken.

FWIW, we also had King make +0.0005" main bearings in addition to the std size, so the main clearance could be in the middle instead of the top of the recommended clearance when building a new engine.

Original cam cover emblems touched up. These seem to have strange finish - almost like black chrome. I thought about replacing with Lee's replica but decided to touch up and reuse.

I will run over and make sure there are no flaws, then I should be ready to ship very soon

Re: Secondchance - 380 build begins!
 

Looks great! Thanks Lee.
Heads are ported awaiting valve job.

I am going to get everthing packed up, the airhorn had a gassing issue so we are redoing it...had some pitting due to gases trying to escape the aluminum. Everything else turned out awesome, will have everything packed and over to Fedex in the next few days.

Will ship the airhorn once its redone

Maybe u know this already, but if that "pad" for the ignition module wasn't masked off before PC, you'll need to remove the PC before mounting the module. Can't tell from pic.

Re: Secondchance - 380 build begins!
 

I would guess the "sub-contractor" had that under control?

Re: Secondchance - 380 build begins!
 

If not, will figure something out.
