my H13 spec called for 230 ft lbs.

Is that the stud I should go with?

You should be using a 3/4 drive to wrench anyways.

Besides not wanting to get a torque wrench, arp studs are sufficient. Being that you're a mechanic by trade, and wrench in your own truck, it may be worth buying a good torque wrench that you'll have forever. No chance of salvaging the ones from your bad block and saving the money?

 

[Stroked777]

The studs are good. Was worried about reusing them. People say you have to torque them higher the second time and I don't wanna crack my block. And we just curious if I should upgrade the studs now to something better

 

[madman1234509]

No need to retorque higher. Plenty of people have re-use them with no issues. I wouldn't worry

 

[Stroked777]

My worry was these studs were the ones that called for 275ft lbs. I really don't wanna torque it to that and risk a cracked block

The amount of torque (based on the reading of the torque wrench) a stud recommends is not a significant factor on whether you will crack the block.

 

[Stroked777]

Weren't people cracked stud holes by using a higher torque

Yes, but the torque you are putting on the block is not necessarily the torque you are putting on the wrench because material and lube are also major factors. Example...install Custom Age 625s to 230 on torque wrench you almost certainly crack the block but installing ARP 2000s you will almost never crack the block at 230 on torque wrench. Another example...ARP 2000s originally used a different lube and called for 325. When they changed to a different lube, they called for 275 and that was on the exact same stud.

I know different studs require different torques and still put different forces on the block. I was just wonder if I'll be ok to reuse my arps and torque them to 275 (is everyone still doing a lower number in the crack prone holes) or if I should do a different stud that will be better to use in the long run

Also what would be a good manual to use for rebuilding my motor, one with torque specs and procedures?

 

[dsberman94]

Just fill the block. Won't have to worry about those spots cracking. Lol

As far as using a different stud goes, even though you're putting less torque on it, it's still providing the same or more clamping force due to the material it's made out of. I think if it's going to crack there isn't much avoiding it, except to not torque them all the way. Only issue with that is it seems like some that don't use the required torque end up having puking issues at higher boost/bp levels.

Everyone has their own opinion. I think there is a lot more to blocks cracking then most say. I bet many of them were from installer error, whether it be using the incorrect sized torque wrench, or a wrench that is not calibrated causing it to overtorque. All it takes is to drop it once to throw it off. I'm not saying some blocks may not be flawed, as people have shown evidence of the casting line being present, I just think there is more to a lot of them. My advice is get a nice properly sized torque wrench, and do it by the book. Look at the new tool as an investment.

We have a nice 3/4 wrench I forgot about in the shop. Goes from like 200 up to 600. The accuracy at the top and bottom ends was about 5% and the middle was around 3%

I have 2 blocks a k16 pump and bunch other 6.4 parts I also have 6.0 manis if ur interested let me know

Ur not going to crack the block using studs, the original bolts are torqued to about 300 to 310

[Stroked777]

They may be torqued to that but it's still less force on the block
I'll let you know about the manifolds, I'm considering doing 6.0 manis

Sorry, I posted that just to state what my H13's were torqued at just for an idea/reference. You're fine with ARP's like madman said. I'd do the 6.0 mani's if I were you.

 

[Stroked777]

If I go 6.0 manis I'm going to try to do the fabbing my self. Shouldn't be bad if the engine is out LOL. Easnt there a thread a while back talking about 6.0 manis? Wasn't there figment issues with the manifold and ac lines or compressor

 

[Black AOD]

I'm not sure about the thread but there will be fitment issues probably, I know my lines had to really be messed around to clear my BD Diesel manifolds and RCD up-Pipes.
