Hard to tell in the pictures but what is the difference in height you see from the stock motor mounts to the AMT ones? I want a set of AMT's but with my MSD manifold I cannot afford to go any higher than my old stockers.
Manifold looks fantastic, going to be a monster sir!!
Tim
Tim, I know you asked Josh but I have the regular AMT mounts and an MSD intake manifold. I have clearance. Here is a pic of the stock mounts next to the AMT mounts. Great upgrade. They are roughly the same size once torqued. Hope this helps somewhat
The AMT "3/8" mounts I bought came in more like .200" shorter on my calipers. They look amazing quality, a little disappointed I didn't get a full .375" but not a big deal.

Thanks Tim! I saw a .200" reduction from stock with the shorter AMT mounts. Very very high quality.
Heavychevy357 and Josh,
Thanks for the information much appreciated. My guess the .200" shorter AMT units are about the same OAH as the stock ones installed due to compression. I cannot imagine the AMT compress much if at all in comparison to stock. The quality looks impressive; love when somebody makes high end stuff with so much junk out there anymore! Mordeth from the forum turned me onto AMT, buying their adjustable camber kit as well.
Heavychevy357 can you comment on any increases in motor vibration resonating back into the car? Any noticeable difference in "feel" of the car. I wish they made something similar for the rear end??

Thanks again Guys!!
As you can see Josh did a much better job by documenting the measurements haha!
Tim, yes there is more vibration after installing. Dash has a slight buzz now. You’ll feel the rhythm of the motor more as well. Feels firmer and tighter despite the added sound(s) and vibrations.
If you have the "red" AMT mounts then you have their std height. I initially had those, but they wouldn't allow me to install my MSD manifold.
Mark, owner of AMT Motorsports, immediately without hesitation sent replacement 3/8" lower "gold" mounts! Real stand up guy & company. The gold ones did the trick, I even added 2 washers, as I didn't want to have the leaf spring touching the oil pan when at full extension.
Like someone mentioned, there is some added NVH, mostly at idle. So a little buzzing of various panels, tingling in seat bottom, etc... But makes the car feel very solid upon snapping throttle!
My red AMT mounts are in fact their 3/8" lowered mounts. The standard height mounts are also red. But they are not the same shape at all. The lowered version that I have has a much more narrow profile than the standard. I spoke to Mark on the phone as he sent these.
Josh, what are the benefits of the Visner lid? Increased plenum volume? Air distribution? Both?
Bigger plenum volume, also the shape I wanted. The shoulders are more pronounced and shaped well for the dual TB flange. I only need minor side reliefs to fit the duals. I tried a carb style lid that I wasnt happy with, the blank model.
