your bound to notice I install links too useful info in most threads,
now obviously not all the info, posted in all threads will be helpful in all cases,
but you'll eventually come to realize the value of reading thru the info links.
theres a great deal of useful info, in those links
info that you might think is useless to you now, but you'll be amazed at the number of times in the future your going to say to yourself...., damn! I remember reading something about that, now where was that posted, and a brief search will turn up your info!, info you swore at the time was a waste of your time to read thru, I know that's been very common for me and I'm sure it will be for those guys that really want to learn how and why things work!.

These specs are for stock-type bolts with light engine oil applied to the threads and the underside of the bolt head. Other lubes, moly, and aftermarket bolts will have different torque specs.

KNOWING WHAT YOUR DOING IS IMPORTANT, TO GETTING GOOD RESULTS!
no one knows everything about all models and years so it helps to have the correct procedures and info in a handy referace source,now you can get by with a HAYNES or CHILTONS manual, or something similar, but for detailed info, OWNING the CHEVY SHOP MANUAL FOR YOUR SPECIFIC CAR IS ALMOST MANDATORY!
I get asked frequently, "how did you know how to do that?"
well, EXPERIANCE plays a big roll, working on similar cars and engines helps, and the INTERNET is a good resource... but theres ALWAYS a big need for DETAILED REFERANCE MATERIAL, SPECIFICALLY MATCHING YOUR PARTICULAR CAR and if you have not yet invested in a SHOP MANUAL for the year make and model of you pride and joy muscle car your either not serious about your hobby, or most likely NOT A SERIOUS HOT RODDER! I constantly see guys SCREWING up installations, or adjustments,if you don,t know exactly what your doing, you need to either let the dealer do it and PRAY his mechanics are experianced and can read, OR..if your like ME, you would rather do it yourself and KNOW its been done correctly...
if your not aware, heres where to order them....

1-800-782-4356

http://helminc.com/helm/homepage.asp?r=

your average shop manual may cost $100-$150 ONCE! but youll easily save far more than that in reduced time and screw ups in under a years time or in many cases on one job vs having the dealer do the work!

IF your going to use ARP main cap studs THE TORQUE SETTINGS ARE DIFFERENT than the original BOLTS, the STUDS ARE STRONGER, BUT,you might also consider that main studs generally install after cleaning the threads in the block with a tap,blowing them dry with high pressure air, oiling the studs course threads with the thread sealant and fine threads end with the ARP thread lube, when you screw them into the block the full thread depth,by hand, then get backed out one turn, the main caps installed and the nuts torqued in stages to seat and hold the main caps, now LOOK at those STUDS the end in the block threads is SAE COURSE thread, the end your torquing the nut on is SAE FINE THREAD with a much different PITCH that requires less tq to give the same clamp loads
Image

Image
http://www.arp-bolts.com/catalog/Catalog.html

Why do they get backed out by one turn? I'm trying to think of the physics behind it, but I can't think of any good reason. What is the physics answer, Grumpy?

the threads must bear evenly and align correctly with the studs center line, for the stud to apply max loads over the total threaded surface ,the threaded section must be under tension alone and engage the total threaded surface in the block, if the stud is torqued into place, you've preloaded the threads bearing the load and they are partly under compressive loads ,your basically jacking the bottom of the threaded hole away from the threaded section, and applying THOUSANDS of lbs of extra stress to the blocks web area if you torque the threads to the same 100 ft lbs the original bolts were tightened to, the threads in the block will now have added stress once the full tension loads on the studs and main caps is applied by torquing the nuts on the studs ,theres added stress on the block, if the studs have bottomed out and are pushing on the bottom of the threaded hole making the block web area more likely to crack or the crank saddles to distort.
keep in mind FACTORY BOLTS are made slightly shorter to PREVENT the bolt tip bottoming out in the hole, but bolts cause wear on the threads because they are tightened while the bolts still advancing deeper into the threaded block, studs cause far less wear because they fully engage the threads bearing the loads before the tensile load is applied

heres what ARP says
"STUDS vs. BOLTS

ARP recommends the use of main studs over bolts whenever possible for several key reasons. First is the ability to obtain more accurate torque readings because studs don’t “twist” into the block. All clamping forces are on one axis. By the same token, there is less force exerted on the block threads, which contributes to improved block life (very critical on aluminum blocks). Finally, there are factors of easier engine assembly and proper alignment of caps every time"

ARP's instructions (for head studs)state that you should thread the studs into the block until they're hand-tight, but with the head on the block, this is difficult. Fortunately, ARP was thoughtful enough to incorporate a fitting for an Allen wrench into the head of each stud. So, using an Allen wrench, I threaded the studs into the head until I could no longer turn the wrench with two fingers. This method seems to have worked nicely

1. Clean and chase appropriate threads in
block to ensure proper thread engagement
and accurate torque readings.
2. All hardware (and caps) should be
cleaned and inspected prior to installation,
looking for any shipping damage or defects.
3. Screw studs into block, finger tight
ONLY. For permanent installation, apply
Loc-tite (or similar adhesive) sparingly
to threads. Be sure and install the caps
promptly before the cement sets to prevent
misalignment of studs in block.
1. Clean and chase appropriate threads in
block to ensure proper thread engagement
and accurate torque readings.
2. All hardware (and caps) should be
cleaned and inspected prior to installation,
looking for any shipping damage or defects.
There are a number of important considerations
when installing ARP main studs.
3. Screw studs into block, finger tight
ONLY. For permanent installation, apply
Loc-tite (or similar adhesive) sparingly
to threads. Be sure and install the caps
promptly before the cement sets to prevent
misalignment of studs in block.

First and foremost is making sure the
block and studs are as clean as possible.
Foreign matter and debris can easily affect
the quality of thread engagement and
cause erroneous torque readings. Do not
re-cut threads in the block – use the special
“chaser” taps as listed on page 87 of this catalog.
This will preserve the integrity of the
threads and provide better engagement.
Calibrate your torque wrench – even new
wrenches have been known to be off by as
much as 10 foot pounds! Use consistent
tightening techniques.
4. Install main caps, checking for binding
and misalignment. Lubricate threads, nuts
and washers with oil or ARP moly assembly
lubricant before installation. Note that torque
specs will vary by lubricant. Moly lube is
most consistent. Have block align honed.
5. Using the instructions provided with
the studs, tighten the nuts to proper
torque values three times. NOTE: If using
Loc-Tite or similar cement, proper preload
must be achieved prior to it setting up.




http://www.arp-bolts.com/FAQ/FAQ.html

I usually use this sealant (sparingly)on the course ends of main cap studs that screw in hand tight, and ESPECIALLY on head studs that enter water jackets



http://www.permatex.com/products/Automo ... ealant.htm

Image



keep in mind the course thread section is not being screwed in or the threads moved as the nut on the fine thread upper end is torqued to spec. and that thread requires the ARP thread lubricant to get the correct stretch and that stud needs to be cycled up to full torque then released and re torqued,a minimum of three times to get the stretch/tq correct

lets assume your looking for a 3/8" drive inch lb torque wrench to tighten little things like intake bolts, logic should tell you that a decent quality tool will not be dirt cheap, and that you don,t need the best available tool for that use so you start pricing your options
the whole OBJECT of you using a torque wrench is to allow you to maintain consistent TORQUE values, do you really think the HF torque wrench will be consistent, when most other sources what 4-5 times as much, think it thru, obviously you don,t need a lab quality tool, but the cheapest option is not likely to be a rational choice either.
