On combustion engines read a interesting article today about the Dura Spark distributor but amongst it was a lot of other cool information including this description of "Ping"
One last thing....when the sparkplug fires, the fuel and air ignite and produce incresed heat and pressure on the piston. The flame front starts at the plug and TRAVELS across the top of the piston smoothly, it is not an explosion, it is a controlled burn. when this event is happening, the pressure on the other side of the piston is growing rapidly and if the plug fires too soon, the pressure on the other side of the piston will increase too fast and start it's own burn which runs across the top of the piston back toward the plug. when the two flame fronts meet, that's what you hear as "PING", and you have lost any power you were trying to achieve...I hope this helps...and you are on the right track.
That's cool seeing rare species. We've got several racer species here. The Coachwhip racer is neat because they have especially long tails that sometimes make up 1/3 of their total length. Not uncommon to catch 7 footers. My favorites are any of the constrictors. Corn snakes, rat snakes, speckled king snakes, etc. They're beautiful and usually very docile. I don't often pick up the racers, because they're especially unappreciative of my admiration. They tend to bite and poop all over me. Btw, the corn snake bit me as I released it. Friggin' ingrate!

Well you DID pick it up, what did you think could happen? It was going to show you appreciation for picking it up. It's a freaking snake, leave it alone. I do not care if you have a Jungle Expert cert or not. Lol JK

Those clowns that instructed at Fort Sherman learned more from me every time I went there, than they did from their little Army jungle manuals. I caught my first snake when I was 4 years old. I got my little a$$ tore up over that too. I've always enjoyed learning about them. People used to ask why I caught them. I never had a good answer until it occurred to me in my 40's...... I would love to catch, examine, and release polar bears, bald eagles, great white sharks, buffalo, lions, etc. But snakes are about the only interesting animals that you can easily catch.
Good news! I drove down to Hammond this morning and brought back the block. They polished the bearings a little, and all is good now. When I got home I removed the oil gallery plugs and thoroughly cleaned the block again. It's now on the engine stand in the shop, with the camshaft installed for the last time (for the first time).
They pretty much did what I wanted to do, but was afraid to do because I'm not an engine expert. If this ever happens again, and I pray it doesn't, I think I've got an idea. It sprung from a joke....when this first started, I told a friend that I'd just build it, and dump a quart of lapping compound in the break-in oil. We both got a good laugh, then the light bulb lit up. I could have just used very fine lapping compound on the bearings, and spun the camshaft until it was lapped in. Of course it would require some serious block cleaning afterward, but I believe that would have worked.

"Tiger Land" @ Ft. Polk was pretty inadequate in terms of jungle warfare training. My grandfathers teachings and woodland tracking experience saved my *** more times then I could count.
Let fun begin now Mike ! I'm excited for you brother. Lots of pics please
Yeah, I'll bet your brothers were grateful for your grandfather's teachings, and happy to have you around.
Soon as I'm done feeding children, drinking coffee, and reading the news, I'll be out in the Bullet Room starting assembly. I'd like to get the crankshaft in today, but I may wait til tomorrow so I can have a helper. It's very heavy, very expensive, and I don't want to risk damage. But I can start gapping rings today.

Patients has proven to be your best friend on this build so far no reason to abandon that strategy now. Having someone to help with that beefy crank is the only way to go. Go team "Scrappy" !
Thanks Brother. That stool is good for the TIG table. See the black thing next to the stones? That's an ocular piece off of a cheap rifle scope. I have a pile of cheap scopes that sometimes come on used rifles I buy just for the receivers. Anyway, you can remove the ocular piece and use it as a loupe. Very handy for looking for burrs on piston rings, camshafts, or in my fingers.

I got all the 2nd rings gapped. My eye (singular) ain't what it used to be, so I set up one of my dual LED work lights above the block. I'm bout brain frazzled now, so I'll stop for the evening. Don't want to mess up a top ring!
The rotating assembly was balanced by Ohio Crankshaft, but my paranoid gene wouldn't let that stop me from weighing everything anyway. Each piston / rod assembly weighs within one gram of 1687.5 grams. All the pistons were within a gram of each other. All the rods but one were within a gram. It was 1.6 grams heavier than the lightest one. I'll match that heavy rod up with a light piston. Now that's paranoia!
I totally get the time put into the build. Any weight variations in the rotating assembly are going to throw it out of balance and cause uneven wear. I was reading this article about FE history and the first high performance 390 they built at the factory in 1961 and what lengths they went to have it be mechanically sound.
That is a lot of eye strain for one day. Pace yourself my friend
Also available upon introduction was a 375 horsepower version that replaced the 360 horsepower 352 cubic inch V8 used in 1960. This new 375 horsepower engine had a block with a slightly different casting pattern that provided stronger and thicker bulkheads than found in the standard engine. This engine also had an aluminum intake, improved oil passages, and grooved main bearing journals to aid in lubrication. The blocks were dye tested to find any weak areas and the pistons were X-rayed to ensure they were up to the rigors they would likely face.
