I had a friend that raced in a class. They changed the PAC springs ever 3 races so i would buy all the pulls. 99% were still like new.

[@arthurrodesiler3109]

You really don't know what you are buying these days. When Crane Cams were still in business I ran the same spring on my BBC solid lifter cam. I ran that spring which was a dual spring which was the spring that ran on all BBC cams up to 580 lift or so. I forgot the part number but still have a brand new set in a there crane box. Part number on the box of new springs are 99893-16. I still have 3 BBC engines with these on them. Ran them springs for over 30 to 40 years ago years and never had a problem. They seem to last forever. I bought there cam kits which were great kits. I still have the springs on my street BBC which has been on there for close to 40 years and it still goes to 7,000 rpm on the factory valves which are heavy. Made in the USA doesn't mean much if they buy the steel from some were else. What a mess we have today. Comp Cams bought out by Edelbrock. Wonder what will happen there? You really need to buy from a good machine shop that is in the know now days like Powell.

ght a set of BBC aluminum winters casting heads used straight from the machine shop. Seller said they have Ferrea valves and PAC springs. Those springs look just like the chinese ones you showed in the video. I wondered how to tell for sure, good thing I never bolted the heads on. THANKS!!!!

[@powellmachineinc3179]

No problem

[@TheJagjr4450]

One thing people need to realize about racing, the reason so many hi rpm racing engines DO NOT BLOW UP in high level racing is because the care taken in the valve train. When they started Xraying the valve springs to check for tiny defects the number of broken valve springs fell drastically. Valve Springs were the least expensive part in an engine, for many years costing less than $100. I think a high end set of xrayed springs runs maybe $500. IT IS $500 WELL SPENT!

I actually very recently saw a broken Pac spring,, same as you it had been coil bound. Wrong spring for the application. Worse it was a name engine builder. The other 15 still measured ok but showed where the coils had been binding. I also saw some retainers that came with a set of springs and some where machined to big to nestle in the springs.

Best lifter to run is the ctsv 88958689 with the ceramic check. I’ve ran them to 8200 with .015 preload and 525 pounds over the nose.

[@george1la]

Great information to add to the cam and lifter problem. I only solved the cam and lifter problem with using DLC coated lifters. And it took 4 cams to get that far. I pulled a lot of metal out of the pan many times. I then had a head gasket go so I got a look at the lifters and cam after use. Each lifter on the cam face with the DLC looked like they came just out of the box new. The cam looked like someone had polished it. Steel does not touch the hardness of a diamond and since DLC is carbon based it is also slippery. When used in piston pins the coating never wears it is the underlying material which breaks. Use a DLC lifter with a new cam and forget having to go roller for your street motor. Obviously, materials and quality control went to hell concerning cams and lifters. Why should they care when they make so much more on every set when roller. Look at the difference in price along with needing new pushrods so they are the proper length.

[@powellmachineinc3179]

Yup

I’m not sure about NexTek, but PAC supposedly got bought out in 2022… I don’t know anything about the buyer, but what happens alot of the time in just about every manufacturing industry is that when a company is sold, they start cutting costs in one way or another. After seeing all these obviously fake PAC springs all over the internet, I recently got a set of PSI springs. Open the box and Fake garbage! I’m afraid there is more foreign LS parts that have flooded the market nowadays and some of the fake stuff is looking more and more real.

Steve Morris has had a few springs break in his SMX engines....and these are premium good stuff...but they've found that the methanol fuel puts a lot of moisture in the motors and if you don't run them up to temperature with gasoline to drive out this moisture they springs will rust. Every one that broke did so at a rust spot that had penetrated enough to weaken them. I agree that the Chinese CAN make good stuff and have had a few positive dealings with them, but always remember that there are deceitful businessmen over there that will change materials to make more profit especially if they don't think you'll notice. They have lots of buildings falling down because they were built with substandard materials so the owner could make more money and I think this trend is going in the wrong direction rather than getting better as their economy is failing badly.

OLÁ. É provável que exista mais de uma especificação para pressão de molas. Examinando as tolerâncias de fabricação do ângulo de assentamento de válvulas e sédes nota-se a possibilidade de "inversão de ângulo". Esta inversão pode ser corrigida com leve retífica de pedra na séde de válvula. Caso não for feita a correção haverá a possibilidade de "flutuar" a válvula na séde não corrigida. Alguns fabricantes de motores optaram não corrigir a séde e adotaram molas bem mais fortes para que com o aumento de pressão evitar a flutuação, mesmo sabendo que diminuiria a durabilidade da correia dentada, dos alojamentos dos comandos de válvula em cabeçotes de alumínio, de aumento de consumo de combustível e de perda de potência.

My issue is, what's stopping that name-brand company from using their box, but putting physically identical springs (made in other countries, not just China) in their box? If they do this and lets say there's 1 box that failed out of 50, it's easy for them to say "oh must have been a bad batch". If they only paid 50% to make an identical product through "China", their profit margin goes through the roof...switching out their parts with Chinese parts (and its not just china). I've seen american made parts fail as well....packaged in a "Made in America" box. When it comes down to it, everything's a roll of the dice. As much as we Americans want to trust in American made products, and are raised to believe that....we can't. Every purchase is a chance we take, regardless of the packaging and how the product looks.
