By using a three step torque method you can insure the bolt threads and the block threads "fit" each other.

FE Technical Forum / Re: Torque and Fuel Efficiency--Possible?
« on: September 25, 2019, 11:29:52 AM »
My father had a '67 Galaxy (new) with a 390
He was a salesman and put 270k on that car. It could average 19mpg when he drove it, about 10 mpg when I drove it.
(That car would light the rear tires up in smoke.)

I built an A scratch 428 that took .060 just fine, but I wouldn't bet on another.

I have sleeved that passage on a couple of FE's. It was a common enough problem that some rebuilders in the 70's did it to everyone of them. I used a long drill bit and followed with a precision reamer, then a light press .001" interference with a Mickey Thompson Chevy chrome moly pushrod, using "wicking" loctite afterwards. The production engines that I saw looked done like a simple piece of 3/16" brake line.
With a reverse rotation engine, oil holes at 6:00 certainly works fine, I have never seen a problem with that. And Brent is correct about the cam bearing oil clearance, it is a good thing to know. Cam bearings are softer and more forgiving than rods or mains using a much thicker layer of Babbitt, about as close to an old fashion "poured" and "fitted" bearing as we ever see today.

Somewhere I have the 427 factory blueprints that Dave Shoe put online some years ago.
They don't leave anything up to the imagination and show the cam bearing holes down.
Admittedly the blueprints were for the side-oiler but I can't discern any difference between the cam operation of that engine vs. the top-oiler. (I think those 427 blueprints are saved in my old work computer and I can probably dig them up, but maybe someone else has them more readily available)
I have always interpreted that the #1 bearing would only fit one way is the "map" for the rest of them. This logic goes way back and was typical of Ford making parts that should only be installed one way. If you get it wrong the oil pressure suffers, especially at low rpm.

Put all the holes down as per #1

« on: September 16, 2019, 12:10:44 PM »
Sorry to see that damage. I have had that same damage repaired on a steel crank and eventually that crank broke diagonally right through the arm. A lot of stress can be set up right there by welding.
(Those "grooves" are a simple variation of Archimedes' pump. Designed to work with the old "rope" seal, a modern seal shouldn't need them. On the reverse rotation 427 cranks it was standard procedure to just polish them off.)

I use a volatile corrosion inhibitor (VCI oil or paper) and bag it.
Put a bit of the corrosion inhibitor in a bag (it evaporates, this is on the paper stuff that bearings are wrapped in. It has a distinctive smell, not bad) and cover the block on the stand or not with a giant trash bag. Seal the bag tight with a zip tie, and it will come out looking like new a year later.
Google has a thousand examples.
You can it from Caterpillar in 5 gallon pails ($$$) for long term engine and tractor storage. They recommend it in fuel tanks hydraulic tanks, crankcases, and gearcases etc. you only need an oz or two. I love the stuff.

It's all good until you lose one at 6000 rpm, only then do you appreciate how cheap they are.
