So many different answers here so I will add my piece, I called ARP directly because these are their bolts they told me 80-85FTLBS which is what i torqued those studs too and i run around 20PSI, and have made a few 25-26 PSI pulls.v as mentioned Do not over torque them as if will yield a negative result and be conter productive.
Just call ARP. Don't go based on what a bunch of people on the internet tell you. ARP makes the things. Call them up, tell them what you have and do what they say.
Remember those guys are only people too, so make sure the guy sounds like he knows what he's talking about, but odds are their answer will be correct vs what you find on the interwebs. There are probably instruction sheets on their site too I bet.
7. Lubricate the stud threads, nuts and washers with ARP ULTRA-TORQUE FASTENER ASSEMBLY
LUBRICANT. Then install the washers and the nuts onto the studs and tighten them hand tight. ARP
recommends using the ARP ULTRA-TORQUE FASTENER ASSEMBLY LUBRICANT that is provided with
each kit as opposed to motor oil. This is due to higher friction on the studs as well as inconsistencies
in the clamping force of the fasteners when motor oil or other low quality lubricants are used.
PRELOAD (TORQUE) RECOMMENDATIONS
8. Following the manufacturers recommended torque sequence tighten the nuts in three equal steps to 100 ft lbs
with ARP ULTRA-TORQUE FASTENER ASSEMBLY LUBRICANT.
Note: 80 ft-lbs is for the 8740 material, 100 ft-lbs for the 2000 material.
Y2k02 so if I understand that article there is no advantage going with arp 2000 bolts. as being able to torquing to 100 ft lbs is the only way they are better than 8740., but 100ft lbs will distort the block.
Mihovetz is definitely the king of extracting huge HP from the stock bore 4.6 block but if you look at posts from guys running the 3.700" bore Boss block you'll hit some that solved head gasket sealing problems with that block by torquing the ARP 2000 studs to 100 ft-lbs and higher.
Another factor to consider is if you are using TFS heads they have a thicker deck surface, its claimed that there is no reason to exceed 85 ft-lbs with the stock heads because of their limited deck thickness.
If I was running on a stock bore block I'd torque them to 85 ft-lbs, on my Boss block I torqued them to 100.
I don't think the 15 lb difference is enough to cause significant distortion of the block.
I'm looking to replace the struts and rear shocks on my 2000 mustang. I was looking at KYB ones on Summit and wondered if they are better than stock. I don't need top of the line performance stuff but something a little bit better than stock.
I'm having a hard time believing that the...
Hello, I got lucky and received a 1993 Crown Vic 4.6 motor that has never been run in it's life and never taken apart either, all the parts are still torqued down and without a trace of wear on the inside. The motor has no Vin or any information about it besides the number on the side of the...
While I had to complete this car in a hurry towards the end, having changed so many things on it and even doing this kenne bell. Nothing replaced the look of joy on my father's face when he saw this beauty, and the reaction he had when I realized I'd given him a full setup with supercharger...
