I can't remember for sure it's been several months, but if I'm not mistaken it was 80 ft lbs...
Paul also told me if I had to distort the mounts metal to hit the number so be it. This applied to the long one's that run through the mounts. I can check my directions for sure if you'd like I still have them at the shop...
I just caught this posting... PLEASE feel free to contact the manufacturer (me in this case) if you have issues with a new part. We are always glad to help out & make things better. A happy customer is our only customer
I am not sure of the torque spec on the long bolt, but the ones into the block get 58ft/lbs. 80 doesn't sound too far off if any. The biggest issue with vibration happens when the side plates on the poly mount don't clamp tight against the stock frame pad. The frame pads are all different in size & shape, so some of them don't bolt right up. If the long bolt holding the mount to the pad is tight, that doesn't mean the side plates are clamped tight against the frame pad. This will rattle much more if it isn't clamped tight. Some cars need a thin washer or 2 between one side of the frame pad & the side plates to allow it to clamp tight.
Our original mounts had "normal" poly bushings, and had a small weld all the way across the part that sits on the frame pad. We found this to be OK on most cars. To let the side plates clamp on undersize frame pads easier, we started to weld only on the ends & not all the way across. We also had a slightly softer poly custom molded up for the prod. 3.8 mounts. We still use the regular poly on the stg mounts due to higher HP potential. Now, we have a spacer pin between the side plates that sits on the frame pad. This lets the side plates clamp on even smaller frame pads. Now our mounts should fit every single car out there, of course someone will prove me wrong
Basically, the minor % of people that had this issue will be reduced or eliminated.
If you have the earlier mounts that were welded all the way across, you may need to put a washer in there to take up the gap. Now that you already had them installed, you may have to bend the side plates out to get the washer in. Clamp the sides TIGHT! Distort the metal all you need, just like the stockers did. It's just a little harder now that they are thicker & stronger. Hope that does it for you. If not, PLEASE let me know directly so I can help you get it figured out. It's hard to get & keep 100% customer satisfaction, but that's the goal!
PS- The difference from having the pair over a single poly mount is actually minimal. You might think that it would double by doubling the mounts, but it is more like 10-20% more. Also, the softer poly makes it slightly smoother, but it is not worth taking the old ones out to swap them. It is just a minor improvement. It might make a bigger difference on cars that seem to have more vibration, hard to say. Every car is different & reacts different to changes. Hope that helps! Oh yeah, they do soften up after 1 week to 2 months of running, depending on how much you drive it. There are some clearances within the mount to be able to assemble it and not make it so tight, and they settle in. Most peole tell me that the vibrations are enough that the driver/owner will notice, but not be annoying or excessive. The passenger, spouse, or friend will most likely never notice a difference. If it's more than that, it's likely the side plates not clamping the frame pads.
Sorry if that was too winded
What i love the most is when im under the hood and i rev it from the throttle latch, just to see my engine NOT move a hair!!! NO tie down strap necessary when these things are in place
