blocking coolant to trottlebody
I have seen people blocking the coolant ports that go to the throttle body and I was wondering how you do it? and is there a better gasket for the supercharger then the Fel-Pro gasket?

LOTS of Mods
Re: blocking coolant to trottlebody
you need to do the 10 cent mod or drill and tap your LIM and also remove the wall on the turnaround
Now if you have done the above and blocked the TB coolant ports, your coolant flow is reduced slightly. In our 3800 motors, it is known that cylinders 3 and 4 (both middle cylinders) run hotter than the other four because they are in the middle of the heat sandwich. I like to increase the flow from the rear head to the front head (thermostat area) by opening up the area behind the endcap on the LIM. This cap is under the throttle body. Have a dealer only rear intake coolant cover gasket (24505049) on hand and remove the two 8mm bolts holding the cap to the manifold.
