16 Pairs Steel Street Locks: 4 Groove, 7° Angle, 3/8" Stem Size

  • Includes 16 Pairs of Chrysler hardened Steel Street Locks: 4 Groove, 7° Angle, 3/8" Stem Size

These hardened steel, Chrysler 4 groove Steel Street Locks with 7° lock angle and 3/8" valve stem size are a perfect replacement lock for stock engine rebuilds. They are recommended only for street applications with lighter valve spring loads. It is critically important to make sure valve locks match the valve size. There should always be a small gap between the two halves of the lock when they are properly positioned on the valve stem. If the two halves fit together without a gap, they are too large. If the locks fit tight to the stem and leave a gap between the middle of the lock and the O.D. of the stem, the locks are too small.

Most people believe that the tang inside a valve lock holds the retainer and valve spring in place while the engine is running. This is not the case. The cross-section of material in the tang is not strong enough to withstand open spring loads of 1000 lbs. or more. The sole purpose of the tang is to temporarily locate the lock, retainer and spring relative to the valve  until the taper of the retainer can nest around the outside surface of the lock. This creates a "collet" effect that binds the two together. The more spring force exerted on the retainer (as the valve opens), the more force applied by the "collet" effect to keep the retainer and lock in place.

Funny, smart and nerdy
Format: Kindle
Are you now or have you ever been a member of a TTRPG group or serious video gamer? This book is for you. You'll get all the in-jokes, understand the process and enjoy the story. It's almost literally a step-by-step description of a dungeon crawl from hell, but I was never bored. Matt Dinniman's tone and how he writes Carl are smart and enjoyable.

Chaotic & absurdly funny!
Format: Paperback, Format: Paperback
Dungeon Crawler Carl was one of those books where the first thought in my head was, what on earth am I reading? And somehow that’s exactly why it works. It’s chaotic, absurdly funny, and completely outside the usual genres I gravitate toward, but it turned out to be such a fun ride. The premise alone is wild. Earth collapses into a giant dungeon run as a galactic game show, and Carl ends up fighting through it alongside his ex-girlfriend’s cat, Princess Donut, who honestly steals the show for me. Like if I ever get a cat I will probably named her Princess Donut haha! The whole thing is nonstop action, monsters, traps, loot drops, and ridiculous commentary about survival being tied to entertainment value. It’s very LitRPG, very Dungeons & Dragons energy, and packed with pop culture references. Did a hybrid read and listened to the audiobook when on the go, which is phenomenal and probably the best way to consume it. The narration makes the humor and chaos land even harder. Carl and Princess Donut as a duo are hilarious, and I can already tell this is the kind of series I’ll return to whenever I need a break from heavier reads. It’s intense, bizarre, and honestly kind of addictive, not something I would jump back to back considering there are like 9 other books, but it is a surprisingly great palate cleanser.

hilarious, fun and fantastic writing
Format: Kindle
It’s been a little while since I laughed hysterically from a book. The writing, top tier, the humor immaculate and the characters, compelling. The story is a mix of satire humor and all around packed with all the things that make a book fantastic. Intrigue, mystery, actual thought. 🤣 For all my booktok girlies who are on the fence, just do it. It scratches an itch I cannot describe.

Doctor Aphra and Luke Skywalker - An Entertaining Duo!
Format: Paperback
I've greatly enjoyed the various Marvel Star Wars series, but Star Wars: Yoda's Secret War left me a little unsatisfied.  I'm very happy to say that the next installment--Screaming Citadel--righted the course and returned the series to its high standard. Of course, this volume is not just comprised of the Star Wars series.  It also has issues from Doctor Aphra.  Obviously, the two comics crossed over with each other to deliver this story as  whole. Doctor Aphra has an ancient crystal supposedly housing the sentience of a powerful Jedi.  She needs the Queen of the Screaming Citadel to access it for her, and she needs Luke Skywalker to entice the queen into doing so.  You'll have to read the book for the details on using Luke as bait.  Doctor Aphra sells it to Luke as a chance for him to encounter an actual Jedi master, and it's a chance for her to witness a remnant of the ancient past because she is an archaeologist after all, albeit a bit of an immoral one. That's a pretty good premise to achieve what this story is really all about--watching Luke and Aphra interact.  I believe Doctor Aphra is one of the greatest additions to the Star Wars universe in decades.  She first appeared in the Darth Vader series, and she won over the audience so thoroughly that she quickly earned her own title.  Honestly, though Aphra works best when pitted against the pure of heart, or at least those on the side of the Rebels.  She's Aphra, so of course she manipulates Luke, double-crosses him, saves his skin a few times, then cheats him again.  That's just who she is. It's also interesting to see a rebellious streak in Luke as he jaunts off with Aphra without telling Han, Leia, or anyone else for that matter.  We know his dad didn't always follow protocol, so these little deviations are always revealing when Luke is concerned.  It's also fun to see him beginning to realize his power.  This particular story takes place soon after A New Hope, so Luke has not yet begun to completely understand what he has at his disposal--though this book does depict Luke having some pretty cool moments with his burgeoning abilities. We also have quite a bit of Han, Leia, and another invaluable addition to the mythology named Sana Starros.  All three get their moment to shine as Han finds more and more of the hero within, Leia further establishes herself as the capable leader she is, and Sana Starros slowly reveals more and more of her past to the reader.  Guess what?  Not only does she have deep connections to Han Solo, but it's heavily hinted that she is also tied to Doctor Aphra as well.  The specifics may surprise you. And, as always, Aphra's versions of C3PO and R2D2 steal the show.  They are named 0-0-0 and BT-1.  They are basically the murderous, demented, evil version of our favorite droids, and they are forever a delight. The story of Screaming Citadel itself is entertaining.  The art is very pleasing to the eye and keeps the plot moving at a quick pace.  At times the faces of the characters based off of real life actors look almost photo realistic, which is sometimes jarring when the rest of the panel does not look so true to life.  Of course, the best quality of the book is simply seeing all of these characters play off of each other.  It's refreshing to have such rounded, charismatic new characters as Aphra, Sana, Triple-Zero, and Bee-Tee 1 making waves with our legendary favorites.

Hokey religions and ancient weapons are no match for a good blaster at your side, kid
Format: Paperback
Star Wars: The Screaming Citadel is a crossover collection of the main Star Wars comic series and the Doctor Aphra series. The Arc revolves around the Queen of The Screaming Citadel being the only one who can open a relic containing an ancient Jedi master. Aphra then teams up with Luke Skywalker and we have our crossover event. The story itself is good. A queen with parasitic bugs controlling a planet is uncharted territory for Star Wars and it works. There were great action moments, plots painting the Empire in a morally grey light than the traditional evil one. Doctor Aphra Marvel's golden girl character was funny in this and her chemistry with Luke worked. It didn't feel forced like Marvel was trying to use the Original Characters to build-up their new ones. Where this comic fails is the inconsistent art style as this is a collection you get different art with each issue. Its starts of good and then takes a nosedive in the Aphra issue in the volume. Bad art aside Screaming Citadel was an enjoyable crossover. Doctor Aphra is the best new character to come out of this new Marvel Disney run. Screaming Citadel is worth the read it was a nice crossover that delves more into the Fantasy elements of Star Wars and works as Star Wars has been Space Wizards since 1977.
