I worked on the original hemi/wedge blocks from world and I pointed out to Bill Mitchell about the studs and he did not answer my questions. I would put the main studs in finger tight and they would still feel loose. You could wiggle them with your finger tips. I never did like them.

With the stud nuts saying ARP, and the cross bolts being ARP, why would we have questioned the studs manufacturer ? An easy way to deceive us. I would have gladly paid up front for the ARP studs.

If the bolt stretched when they were tightened before boring, when they are replaced, the size & run-out will be different. I am just curious if anyone has checked.

I just went to the shop and looked at my brandy new cast iron hemi world block that got delivered yesterday - shipped AFTER they were made aware of the stud issue. Side fasteners = ARP, main stud nuts = ARP, main studs = One Hung Low foundry, Taipei. The studs are going in the trash and I'm biting the bullet for ARP studs. What a bunch of cheap jerkoffs. Other than the idiot corner cutting, it looks like a nice piece.

When this post came up i spoke with Dwayne and he stated that the main studs on mine torqued up fine. He stated that the studs are good and not to worry about it. This is not a full on effort and if it were i would have better hardware in there anyway....including the crank & rods. Perhaps World has changed suppliers in the past year ? That could certainly account for the soft metal fastner that a few of the reputable engine builders have described. Ron

Between inexperience, in a rush, "thinking" it didnt feel right but using them anyways, not knowing, or lastly just not caring, they are out there.There seems to be some that may be different or ok, just dont know when. It would have been very easy for some to just use them and not really know what they were experiencing.The design of the bad studs is just that, bad. No comparison to the rolled ARP threads, undercut, chamfer etc, not taking into account the actual tensile strength , hardeneing or overall soundness. I have already changed out several "studs only" for the mains, as well as gotten new complete kits for members here and my own clientelle. I think if nothing else, they all are resting better. The " bad" ones really are BAD. RIP Monte Smith Your work is a reflection of yourself, autograph it with quality.

I dont plan to take the engine out of the car now that its running, take it apart, replace the bolts and hone the block if needed. I had no torque problems during assembly, the bolts did get cycled 3x's or more.I will replace the bolts at a later date during a routine freshening....I hope...

I did a google search and vendors have them for aprox. $5.50 each. Last edited by Teamx; 09/01/10 04:23 AM.

CompWedgeEngines master Joined: Nov 2004 Posts: 3,544 Syracuse,NY	That is correct, and your part numbers are correct. I posted way back in the post the part numbers for new stud kits. I dont think the side bolts are of any issue. Everyone can make up there own mind, make their decision based on whatever it is thats important to them, and move on. I am burying this dead horse from my perspective, because their still seems to be people that dont believe this is an issue or dont believe the findings. We all have our own opinions and choices. Good luck to all. RIP Monte Smith Your work is a reflection of yourself, autograph it with quality.
