Hello Brian.
I have been thinking about installing those pin sprayers, but I am not sure if I would need them.
I would like to install a spray bar on top for the springs though, Being I am partially filling the block I thought that anything that helps keep the motor
cooler would be a benifit.
As of now I have:
A larger radiator out of a dodge V-10 truck which sits in the bed of my truck. I used custom bent 1 5/8" conduit pipe that is run from the motor
down along the frame and up through the box into the radiator. That added about an extra 2 gallons of antifreeze over the stock system. My motor never got hot.
The trans cooler is also in the bed of the truck.
I am adding an oil cooler with 8an fittings as a upgrade with this new build .
