Here are some posts of those who have installed it:

Just got my shorblock installed that I had built by BBR and shipped to me over here in Germany. BBR recommended this cooling mod since I have a blower setup. Literally took me no time at all to install. And once I got this installed I noticed that my ECT's have dropped a noticeable amount from my Aeroforce gauge by almost 10 degrees in traffic and noticed on my instrument cluster as well that it's cooler. This a great way to keep the engine cooler for less detonation and I would recommend this for any new Coyote 5.0's for some good insurance for your investment. Thanks BBR and MMR.

We have installed this a couple cars in the last couple weeks and sent some over to our boys stationed over-seas. What we have noticed is that the cars ECT's have stayed cooler. Now we have not done any serious testing because the motors that they went in were all new built ones going through seating of the rings but we are looking forward too see the final result. So far, we trust this product very much and if your swapping out the motor, we deff recommend this mod!!

As stated above this can be done in the car with the intake removed. I used a chisel and a small pair of channel locks and had it done easily. Thanks again MMR for a quality product.

Can this be installed with the motor in the car?

Sure as hell doesn't look like it.

Lol I know that's y I asked

it can be installed while in the car. Clearance is tight, but you can knock out the freeze plugs and install these with the room available.

Sorry for the late reply guys, our tech staff that answers the questions here on the boards was not in the office last week.

The simple answer is yes, they can be installed and it is not difficult. Please let us know if you have any other questions!

I'm no expert, but sales might jump up if a few cnc'd aluminum bits weren't running damn near $200. It's your business and you can charge what ya wish, but the general consensus seems to be that sales would increase if you were in the $125-$150 range.

Do you have before and after data logs of temps?

I would like to see some data before shelling out money.

How do you tap out the freeze plugs with the engine in the car? Seems like you'd have no room to "tap."
