Like new condition maybe 500 miles in the car.

Using this down time while waiting on other parts to go back to the stock ones.
I’m sure they do the job but the vibrations just take the fun out of the car, it always feels like something is rattling.

Will have pics and a low price in the for sale section shortly.

If you drive yours a lot and are in the fence about these, don’t

I was thinking about changing over to these. Didn't even think about more vibration. My car already vibrates with the cam. I am guessing this is going to really increase it. I have something else to keep in mind if I decide to pull the trigger.

I just sold them to a member on the forum. As for vibration I had solids on a 454 but I think the stroke duration was so different is wasnt a big deal. He is using them on a 427 so there should be more stroke there also. The LSA just "buzzes" the car when super tight.

Also want to add the cam shakes the car more with the stock mounts then the polys since the engine will make momentum side to side. With the poly its anchored in place and at idle it feels smoother but as soon as you start moving there is vibration and harmonics based on rpm and whatever is loose in the car.

Not horrible just not for me, much more fun with the stock mounts and i can live with a lot, big cam fluctuations and power gaps, noise, etc.
