It's kind of funny. In the diesel world I shun ARP studs in applications that truly need studs IE 45 psi or more, unless on a 6.0 ford then stock pressures need studs. I refuse to use ARP's on any ford diesel motor. If you think ARP's are expensive take a look at H11 head studs. Never seen a H11 blow. I have seen them shipped with no threads in the nut (along with some arp's that had the same).
My H11's were roughly $300 more than the ARP's, and thats at cost not retail.
However in a engine not running as high cylinder pressures as a diesel (18 to 1 plus 70 psi in my case). I truly believe a properly installed stud is just that. All you are doing is extending your torque onto a smaller surface area to get a better clamp. Once again as long as they are installed properly. I'm also a stickler as to how many threads I have above my nut on a stud also, so call me crazy.

Well damn I must have been stupid to put these studs in my 408. Haha not. Honestly, it's a fuggin stud. If it torques and holds the torque then what's the problem. The set looks the exact same as arps. Hell the metal arp gets is probably Chinese. If Chinese steel is worse than millions of people in the bay area should be nervous. The new
Bay bridge is all Chinese steel. Oh no! Just like a fast intake is better than a typhoon. Just like everybody needs konis. It's all propaganda. Hell I have an extra set of the eBay studs. How can we test their strength. I'll put em to the test. Someone let me know!

Haha its funny how everyone gets their panties in a bundle about chinese stuff, i use to be one of those people. But its to late and i dont care anymore look at your kids toys where is it made china. Im a tech at a gm dealership, do you know how much chinese stuff in on your new silverado or camaro you would be amazed. Its the governments fault they should have passed a bill to prevent this and now its too late. Now since all the good paying jobs went to china now people cant afford made in USA products. Look at when holley monopolized, now alot of the products are made in mexico no one complains about that. I live in Canada and there is hardly any performance parts companies here, so in a way everything on my car is from another country mainly U.S.A.
lol.Thats another subject. I agree, everything is made overseas. How ingnortant some people can be to say all USA made parts are superior to overseas. EVERYTHING is made overseas. A man in Japan is just as capable as anyone else to make a good automotive product. Hell the wheels on your car are imported.
Like I said, I guess I shouldn't drive on the new bay bridge because the steel beams, nuts and bolts, and even the floating barge crane are from china. And they believe that this
Chinese steel will take a 8.5 earthquake. An 8.5 would put more torque on that bridge than any of our cars with arp bolts. My .02

85 ft. lbs. isn't always 85 ft. lbs.. What kind of lube are you using? how long are/ is the object your exerting force on? think of putting a piece of pipe on a ratchet, 150 lb.s of body weight on a 10" ratchet is a bunch, now put it on a 10 ft. piece of pipe, it's going to do a lot more, think leverage. Hence why a stud is better than a bolt. You have less area you are applying a force to as opposed to the entire length of a bolt your actually stretching. Amazingly lube has alot to do with how much torque is required. ARP lube, 30 wgt. oil, or antiseize?
Rod bolts are properly done by stretch not torque for this exact reason. torque really is a bad way to measure things as there are a ton of variables that come into play. Whereas stretch you have one variable.
Not being a dick or a smartass, please don't take it that way. but if 85 ft lbs. is 85 ft lbs. then it wouldn't matter if you had a bolt or a stud its still 85 ft. lb.
I havent used the Ebay studs but I think I will for my build.
Opinion time:
I HATE the argument that you get what you pay for. That would imply that when I paid top dollar, for a top of the line item, from a top of the line vendor, whos selling this top of the line manufactures, top of the line product..... That would then mean that I got what I paid for: The BEST and that I would then reap the benefits / intangibles that come with buying the best
I have pissed away thousands of dollars on buying the best and being disappointed. I have also pissed away money trying to be cheap. I have been very pleased with some top of the line high dollar items, and I have also been pleasantly surprised by some budget items.
The messed up part about a thread like this is that the "get what you pay for" birds flock in just hoping to see one case of a real failure. Then that usually winds up being a my friends buddy blah blah blah deal. The guys who have actual experience with the item and say they are pleased with it get drowned out and basically ignored
.
Some one should start a "Who didnt get what you paid for thread". You would have hundreds of inputs and they would be first hand not my buddies blah blah crap.
My opinion on the studs themselves: We are talking head studs not rod bolts. They need to clamp the heads to the block and maintain that through multiple heat cycles. One poster said he has been running them for three years. It sounds like they should atleast be considered a budget alternative to the arps.
