Alright, I've discovered a place where I can concentrate all my non-GMT400
wrench-swinging nonsense in a single stream of consciousness.

Although the reader may or may not comprehend what the underlying
thought process was, I'm hoping that at least some of the following
will either entertain and/or provide some food for thought.

****

Getting engine parts clean enough for a quality build

Ever since I was old enough to wander out to the garage in
the evenings to watch and listen as the old guys would swing
wrenches & bench race while drinking their Lone Star beer(s),
I could sense the unspoken passion that drove these
hard-working folks to spend precious free time working
on their rides.

And the conversations would always start off low-key, and
the participants would almost act like they preferred silence
to the spoken word...but as the brews would work their mojo
on the elder's speech centers, inevitably the conversation would
take on a life on it's own.

It was like watching Gearhead Opera, the natural ebb & flow of
an unforced conversation amongst friends, complete with a little
salty language sprinkled in as verbal exclamation points. (That
stuff just flew over my head, and I just figured that these
forbidden {for me} words were salty dog code for the
listener to pay very close attention. :0)

But in most (but not all) of these conversations, one of
the participants would describe something of breathtaking
beauty that they had made with their own 2 hands, and
then proclaim in absolute terms:

" It Was Clean Enough To Eat Off Of !"

And I'd watch the entire assemblage nod in deep approval.

****

Well, hearing this phrase time & again made a lasting
impression on me. While tinkering with Briggs & Stratton
& Tecumseh motors in 9th grade Power Mechanics class,
I started to understand why the old guys got so excited
about putting together an engine that was clean enough
to eat off of.

(Years pass.)

Thanks to driving a series of '1 car payment cars' (well
used Mk. 1 Fiestas) I was able to siphon off a little of
the auto budget & invest in a 5-gallon ultrasonic parts
cleaner, followed by a Skat Blast cab that I would
fill with crushed walnut shell.

And between those 2 primary cleaning widgets
(+ plus all the other normal cleaning steps) I was able to take an engine
that we had a balance & blueprint performed by our machinst,
and end up with this:

Buttered Toast, Grits, Scrambled Eggs, Canadian Bacon, & Coffee

And yes, I ate every single bit of that, in honor of all the old dudes who regaled me with tales of this.

And I lived to type this in.

(Take that, Cali Prop. 65 Alarmists! :0)

Nooks & crannies don't stand a chance against 100+ psi crushed walnut shell
You must be registered for see images attach

You know, I never did find out if those walnut shells were certified Organic or not prior to use.
(Shhhh - don't tell anyone, it will be our dirty little secret.)

Q: How did I learn about this cleaning method?

A: The jet engine shop guys were all about the walnut shell. I thought that they were goofing
on me as one of the flightline pointy heads, but they insisted it was for reals.

Q: Are you satisfied with your current cleaning setup?

A: Of course not. I would love to get ahold of an old claw foot bathtub, line the inside with
ultrasonic transducers, and drive them at the resonant frequency of water molecules with
a couple of big honkin' Phase Linear amps. No longer only getting to ultrasonic just the
moving bits, now I can ultrasonic the entire block after a good shellin'! :0)

BONUS PHOTO FOR THE BOWTIE CROWD:

Never before opened Chevy 400ci small block heading into
the blast cabinet for a righteous walnut shelling to see if
it's even worth taking to the machinst for boring:

Glad it didn't drop. That would have been a serious injury. Yeah, serious injury. I'm a good driver.

That just about covers that. Seems crazy...but so does the fact that any/all debris left inside
the engine always, always finds the most expensive places to wedge themselves into and
create concentrated sadness.

Well, I too have heard that expression all of my life, but I've never seen anyone actually do it!
Same here! Try as I might, I couldn't even find a photo on the
interwebs that conveyed what the old ones were describing, so
I took it upon myself to right this wrong for posterity.

BTW, after the photo shoot the food had gone cold...but
determined to both document AND enjoy the meal, a few seconds
with the shop's MAPP gas torch and Voila! Haute Hot cuisine! :0)

The flowers are a nice touch.
Thanks for noticing! The thought here was that I wanted the
casual observer to infer that this photo was all about the
celebration of arriving at a long-awaited destination...instead
of a gastronomic punishment for picking the engine building
hobby. Kinda along these lines:

Note the little bits of fresh vegetation on each table. I haven't been to too many classy joints...but when I do go, there's table accents like so.

Thanks for stopping in & commenting -- cheers!

Helping a Buddy to use a once in a lifetime Get Out Of Jail Free card

Back in the spring of '22 I had an old friend contact me after several years
of radio silence. A good friend, the kind where he's a cohort in crime,
but then life outside of the car hobby happens, you fall out of contact...and
then years later, you reconnect, picking up where you left off as if no
time has elapsed since before.

You know, the brother from another mother thing. :0)

Anyway, he mentioned that he had a stalled fun car project that he wanted
to restart, and would I be interested in getting involved? We kicked it around
at length, and once the dust settled, it was obvious that in order for the
project to fit into his household budget, he needed to clear the financial
deck so to speak. Liquidation Sale time!

'18 RAM 2500HD, Big Kahuna edition -- prepping the truck like it's going to the Syracuse Nationals in order to sell, sell, sell!

Success! Buddy's perfect world goal was $50K...but he actually got 109% of that from the dealer that originally sold it to him? The used truck market in 2022 was nuts!
(NOTE: And at the time Diesel had spiked to just over $6/gallon in upstate NY!)

It was a perfect jettison. Instead of a truck payment larger than his mortgage payment,
he paid off the note, plus all the revolving plastic, bought a $2200 beater (cash)
...and put a nice chunk into savings.

When he stepped off that financial hamster wheel, you could see the weight of the
world coming off his shoulders. Made polishing all that endless paint well worth it! :0)

I'll describe the sleeper project in a following post. It's stoopid. But you already knew that.

Cheers --

This made my technical heart smile. This… this giant ultrasonic cleaner. I need this in my life.


I could not get a 55gal drum filled with water and purple degreaser to boil with a turkey fryer as a heat source. That was very disappointing because it meant I had to hand clean parts (rear axle housing, transmission and t-case) of a 65’ international, that had appeared to have been leaking since about 67’, While also being used as a wet weather farm truck, never washed, baked in an industrial oven, and had its gear oils replaced with an NLGI4 grease.

Your wait is over. Actually, the 'clean enuf to eat' photo was taken during a
mid-life engine refresh/upgrade about a dozen years ago. (AFR headed 306ci SBF
with high lift/short-ish duration (.589"/.602") solid roller cam, balanced & blueprinted, zero-decked,
12lb aluminum flywheel, Performer RPM intake, Holley 4-bbl w/annular discharge boosters, fresh
rings, bearings, & gaskets, T-5 tranny, 8.8" 3.73 posi w/F-150 preload spring, blah blah blah.

Who cares? The punchline is that the car features a power/wt ratio of ~6 lbs/hp with me in it.
Definitely not the fastest car (thanks to the gaping radiator opening up front) ...but it's one of the
quickest cars w/right now throttle response. Perfect for enjoying the twisty back roads in the VT mountains.

The idea wasn't a single big HP number. Instead, build a motor with a big personality/immediacy!

The first start? Choppy/thumpy, combined with just a hint of your favorite diner on Saturday morning.


I like Big Barns & I cannot lie:

Big barn ~15 minutes south of Burlington, VT on I-89N side. A big-boned 4-story beauty. Towers over the ~1 ton (curb wt) Cobra

Manchester NH -- '22 Cruising Downtown car show --
FF Cobra replica now old enough to drink in a bar...but still zings to the top of the tach!

Now to figure out how to get my '99 C2500 chore truck to hustle just a little more like this thing.

NOTE: This color is 2000 Corvette Millenium Yellow. The last photo with a modern camera
best captures the rich hue that this translucent multiple-coat paint delivers.

Built, not bought...more or less. :0)

Here's some Cobra replica photos that you don't normally see. I want to try to
share what it's like to set up a V8 powered go-kart for optimum mountain
road enjoyment.


A view of a VT back road from behind the wheel, sitting just inches above the pavement. The CG is muy bueno thanks to aluminum heads & lightweight body.

Note: The tach we chose for the dash only goes to 7000 rpm. On purpose. This way, when we drive the tach right off the scale this helps to intensify the whole acceleration experience for the 1st time passenger. (As opposed to picking a big dinner plate tach that goes to 11, which promises the moon, but in the real world the needle swings
slower & can't be driven too far up the scale before you scatter the motor. Sometimes you have to cheat in order to maximize the motorhead's Theater of the Mind. :)


All Cobras have the engine set back as far as possible per Shelby. The upper radiator hose
is ~the front of the engine block. By contrast, in the old 5.0 Mustangs the engine bisects the
front tires. (Necessitating not one but 2 oil drain plugs in the engine oil pan!)
Here, all main drivetrain weight is located inside the 4 tires. (!)

versus Cobra driveshaft.

The closer that all your weight is to the center of the vehicle the better the polar moment of inertia.
In English, once you've chosen a line through a corner with a Mustang you can't change your mind.
Same powertrain in a Cobra (except the driveshaft) ...and you can change your mind and live
to type about it. :0)

Note also 1/2 the weight on top of similar size tires = better dynamic traction.
(ie: It's easier to get the tires to do more than 1 thing at a time with the contact patch.)
Interstate lanes feel twice as wide as they need to be. On winding back roads the car
feels very light & tossable. There's a reason why that old chicken farmer's idea worked
so well & became such a sought-after ride. (ie: Mere mortals are priced out of the original
Cobra market, and instead will work nights & weekends for 13 straight months in order to
get a reasonable facsimile to drive.)


Stock cast iron F*rd flywheel = 24lbs. This aluminum flywheel = 12 lbs.
Not having to store energy in order to get car moving allows a more dirt trackish vibe.
NOTE: This flywheel was involved in the mid-life balance & blueprint upgrade. Silky smooth
except for the idle, which now has a little more crackle/cackle to it. It also makes the
engine explode to life, which always startles normal everyday folks.

After strapping them in with the 5-point harness, this sudden starting of the sidepipe stereo
seems to cement the deal, and they get that wee bit of a fearful look in their eye.
The stage is set. Perfect.

Note: I used to own a little convertible 2-seater Fiat 124 Spider. What little it did, it did so well.
And that puny little italian DOHC 4-cylinder would make a big deal in a joyful way out of every gear it
climbed through. The more I wound it out, the more it sang it's happy song. (Think of a small 2-stroke
dirt bike engine giving all it has.) What did I learn from that little Spider?

That when you don't have an unlimited budget or unlimited displacement to work with, consider trading
off a little bit of the skull-crushing brute acceleration way up high and instead build the motor to have
a more enjoyable, more 'willing' personality, especially where you spend the majority of the time
during the everyday drive. Build as much 'fun' as your situation allows into the motor, and it will simply
be driven more...and in the end that's the real goal of this hobby -- getting out there and enjoying your
concoction! :0)

Little things like this flywheel, a bit shorter duration camshaft, fussing over the advance curve, and a carb
w/annular discharge venturi all come together in such a way that the engine feels almost anticipatory,
where the torque comes on right now like an oversize electric motor with the start capacitor in circuit. :0)

****

By the way, all of the above is pure heresy to the Pro-street crowd. Mother Thumper cams, oversize
everything in order to make sure that you are threatening mo' power than all the others.

You know what? Great looking but ill-behaved cars spend 99% of their time parked in the garage.
They Overpromise & Underdeliver. If you think back to your very favorite truck, car, or bike, whatever
you wanted to do...it did too.

Food for thought. Thanks for stopping by and checking out my concentrated nonsense.

Cheers --

This makes me want to get my Sunbeam Alpine running.
Don't expect me to talk you out of that. Remember those old BMW ads?

(Re)build yourself a Decompression Chamber for having Persisted/Survived Your
chosen path through Life. :0)

By the way, I like the looks of the Sunbeam Alpine -- reminds me of my mom's
old '55 Thunderbird. Definitely not yet another lookalike bar of soap on the road. (!)

289, right? 4.00" bore x 2.87" stroke? A set of beehive valve springs & other
stealth upgrades (modern aluminum heads painted to match the rest of the engine?)
...and that car would be an absolute hoot!

Yeah, I definitely can't talk you out of doing that. I can't keep all the fun to myself.
(Momma said "We Have To Share." :0)

One last thing. Perfect early quiet Saturday morning. Photographers would refer to it
as the Golden Hour. All your chores are done. Time to get a coffee at the diner
and look at the photos in one of David Vizard's books one more time.

So you decide to act on this urge, grab the book and the keys, and head out the
door. And then you see the little Sunbeam waiting to go out & play, and
you can't help but utter "Ohhh, Yes!"

NOTE: Said exactly like this at ~0:46 seconds into this video.)

After spending a lifetime doing what you had to do on other people's terms...it's
now high time to Enjoy The Toys!
