    Is it ok to copy a W5 head and make it better or are we just mad at Speedmaster

    Volume is the solution to price issues. Expensive parts are usually expensive because the batch runs are smaller numbers which is often set based on cash flows and credit limits of the seller. Why this applies less to china built parts is for a different forum. Even if the quality was...

    Is it ok to copy a W5 head and make it better or are we just mad at Speedmaster

    It's not even close to the same situation. There's no current source for a w5 type head and the original supply is flawed and was a low volume offering. Making a "copy" isn't going to impact anyone. Cheap copies of legit parts that are still being made are an entirely different matter...

    The fact that they've gotten into permanent mold castings is another good sign. Permanent molds cost a lot more and the equipment to support them even more so, but the quality is much higher and repeatability is greater which makes thinner walls and precision geometry much easier to produce...

    speedmaster stuff pulled from Summit racing shelves

    I've experienced it enough first-hand to know exactly what happened. Someone at speedmaster sent a legit part to a shop in China and said "Make it like this", and so they did. Most china based companies couldn't even figure out how to make the part from drawings, almost everything comes from...

    speedmaster stuff pulled from Summit racing shelves

    I think, I know it's poor QC. Some of it is just the process. Most of the mopar parts are sand-cast versus permanent mold. Sand casting can produce good parts, but worn or neglected tooling results in more tolerances and of the processes they run, sand is probably the most variable. As a result...

    Claiming made in USA doesn't really work that way. Typically these days it's a percentage of the final value of an item. If a $2 chinese casting gets turned into a $100 final product, then it's "made in usa from global materials" or some BS. But they can't make 51% of their parts domestically...

    speedmaster stuff pulled from Summit racing shelves

    Due to environmental and emissions laws, places in CA, Oregon and WA rely on recycled material to reduce some of the energy overhead of blending their own alloys. A356 is also used in most every automotive application and so getting recycled material domestically isn't tough. Most raw aluminum...

    I don't think they were ever patented in the first place and protection would be near non-existent. But I do know it's not a copy of a stock head, the castings between aluminum and iron have to be internally different for multiple reasons. But to me, copying them with the sole intent of...

    Their cast alum parts are domestic. They are their own foundry. Some of their stamped items are imported.

    I've got a few dozen patents. Been through lots of litigation. Even people who think they understand them often don't and rarely will even two patent attorneys agree on anything. Patents also aren't cheap, and good ones keep costing money. Last I checked, Edelbrock didn't make iron heads and...

    And unnecessary. No reason to avoid imports altogether. Lots of excellent stuff comes out of other countries who aren't strategic enemies and who aren't making direct copies of other people's hard development work. Most aren't making Mopar parts though, LOL.

    Knowingly violating IP laws is a much eaiser prosecution. It's still not at all cheap though, so the juice has to be worth the squeeze. Summit stopping the sales will basically immunize any claims of knowingly selling counterfeit items that people would have and summit can sit back and point...

    I don't disagree. Good on Summit, they could have stopped at only pulling things they knew to be illicit. But we'll see if they add stuff back later, that will be the real signal they give a damn.

    Nothing wrong with imports in most cases. It's when the money goes directly to a political adversary. Chinese companies aren't mom and pop shops, they're propped up by and run at the behest of an adversarial government which is... not good. Pretty much any other government is better to deal...

    Has nothing to do with a suit from the original supplier. He's screwed no matter what. That doesn't mean customers wouldn't inundate summit with returns and even returns of spurious origin, or begin dragging their name. It's a calculated move. Goodness of heart has nothing to do with it...

    I don't speek ghetto, so I'm not sure what the search term of the day is, but for years there have been a few hundred thousand auto sears for glocks and rifles shipping in from alibaba and wish. In fact, Chicago is now using that as grounds for suing glock. I'm sure the feds didn't turn a blind...

    No they won't. Bare minimum it would be a million dollars for him to pursue a suit, and that's before discovery and trial. Been down that road, there's nothing to gain if you can't prove losses of at least a few tens of millions. Even if some lawyer took it pro bono speedmaster would just...

    speedmaster stuff pulled from Summit racing shelves

    Lots of stuff I've been involved with has been knocked off overseas. The government knows, has the tools to mitigate it, but doesn't care. Patents and copyright are useless to enforce anything to do with China. Getting a judgment is a long process and costly, collecting on a judgement is...

    SUPER CHARGER BIG PAIN IN THE A**

    Doesn't mean it got boxed with all the right parts. I'd call the Mfg and see what they say. Might be as easy as them sending the proper spacers and brackets, might not, but I'd start with them.

    Sounds like new drag racing, donut circuses fines going up.

    Most all of the cars are stolen. The damage is part of the thrill for these hooligans.

    Parts Cache Value…

    One other way to think about some of the stuff is trade value with builders and machine shops. My late uncle built some wicked engines and transmissions for race cars on a social security budget because he could get his hands on seemingly random parts and peices to trade to class racers or...

    Low speed torque and driveability ?

    Exactly. If enough lown is lost, it just means the build needs to be setup to take advantage of where the new "low end" actually is. A car that idles at 1500 probably won't cruise at 2k real well, LOL. But with proper setup, no reason it couldn't go merrily down the highway at 3 or 4k. It's...

    Low speed torque and driveability ?

    My 408 has an advertised duration right around 300 and doesn't like to live under 1600rpm, but will happily cruise the back roads at 1850+. A moderate hill and I'm more comfortable at 2200. It's a 4spd, so it's a little different animal than if it was an auto though. Back when I had the 318/904...

    Low speed torque and driveability ?

    I think the whole "driveability" deal is a function of the fact that most hotrodders for the past several decades have built with an automatic transmission and for a long time it was much more difficult to get a converter that worked well with anything but a mild cam, and especially if it was...

    Low speed torque and driveability ?

    Exactly. My 4 banger econobox cruises in 5th at 4500-4800rpm, doesn't bother me a bit. My busted *** old suv feels like I'm taxing it if I cruise over 2800rpm. My Dart annoys me over 3500 rpm and when I honestly assess this "driveability" metric it really only comes down to noise and harshness...

    Stroker Plugs

    Tfs instructions list autolite 3924 which supposedly crosses to RC12YC or FR5. The next colder is a 3923, which supposedly crosses to RC9YC or BKR6E. I've got a set of tfs heads on a 408 shortblock at around 10:1 and a hydraulic flat tappet at 295 adv duration running the 3924 plugs with no...

    Yellow Optima battery question

    I've seen more than one optima burst into flames if it's given too much current. Jump starting them can often deliver excess current as the alternator maxes out once it's fired off. Might not happen at idle in a classic car, but once you give it some revs it might get dicey. Trickle charging to...
