I have a future project in mind that I would want someones a opinion on.
My dad has 1990 Mercury Grand Merquis with a 5.0L gasser in it. the car is in awesome condition so I think it would be a good candidate for a swap.
The plan is to find a bread truck with the 4bt in it with an auto I believe they but 400 gm trans. in some of them. Pull the motor and trans. and scrap the rest.
I believe the 4bt may fit, but may require fire wall and hood modifications.

Cummins 4BT Vibration
I put a 1986 Cummins 4BT in my Jeep J10 pickup. There was vibration at cold idle, but it was smoother at about 2000 rpm.
I used Dodge 6BT 1st generation motor mounts. I also installed a set of Gaberal air lift shocks on the front, they smoothed some of the vibration.
Last, I installed a 1st generation (Dodge 6BT 12 valve) silicone filled harmonic damper from Fluidampr. Now I have very little cold vibration and no highway vibration.
From what I have learned the silicone filled dampers work best. Cummins makes a 'B' series silicone damper and there are some aftermarket dampers for the 6BT.
The damper I bought from Summit Racing was around $450.00. I don't know how much the Cummins damper is or how much the other aftermarket dampers are.
