Got the oil analysis today. Looks interesting in that it shows iron wear. That could be the cast iron rocker arms where they were grinding away at the valve stem tips. The high lead is from the leaded fuel most likely. My SD455 had similar high lead readings from using the same leaded 100 octane AV-Gas. Though the bearings on the 460 were down to copper on the mains. The machinist said the bearings looked like every other big block Ford he has taken apart over the years.

Picked up the major stuff today today. I dropped off the exhaust manifolds to get surfaced. Years of blown out exhaust manifold gaskets pitted the mating surface on the manifolds. As you may have guessed it, the dealership would just charge my father for replacing the donuts in the exhaust pipe to manifold flange and call it a day, completely ignoring the actual cause of the exhaust leaks...and the noise.
I highly recommend Rogers Speed Shop in Garwood, NJ in case anyone needs any machine work done. They are an old time machine shop with experience that goes back at least five decades. They have done the machine work on all my Pontiacs over the years. They know Fords too (and Chevys of course). https://www.facebook.com/Rogers-Spee...6305069751697/ Last edited by njsteve; 10-08-2018 at 07:06 PM. |

Don't you just love the look of freshly machined parts?

They smell good, too! I had to oil them all down quickly as it was raining when I got home with the parts today.

Interesting Oil analysis. My 03 GMC Yukon XL 2500 had high Lead content because Chevron 94. I dropped to 91 Octane and Lead ratio dropped significantly. I use Mobil 1 and change at 4500 mile increments.

Got these back from Rogers Speed Shop today. They were able to clean up the flange area nicely. They should seal well now. The Clevite 77 main and rod bearings arrived as well as all the new cast iron rocker arms (@ $16 each - that hurt! This engine uses a unique style of rocker arms instead of the $5 stamped steel rockers). The ARP hardened oil pump drive arrived via Amazon this afternoon. I think I actually have all the parts to assemble this now.
The funny thing is that I pulled the engine to get the transmission rebuilt and the tranny is still sitting on the dolly in the garage. I was going to wait until the engine was assembled so I had less time for the rebuilt trans to sit and use up warranty time in case there is an issue with it later.

Chased all the threads in the block this morning. Then I installed the rear main seal, bearings and crank today. Oil clearance is .002, checked with the old Plastigage green. Nice, leisurely day in the garage.

I checked all the ring gaps in the cylinders today. All top rings were .024 gap. All second rings were .028. Got everything ready for piston/rod installation this weekend.
