Coolant Line Under Intake Manifold?
Is there one that runs underneath the LS1 intake manifold or are the rear coolant ports plugged? Curious for purchasing an LS6 intake manifold whether or not I will need a new front coolant line and some rear plugs.

The 97-2000 model LS1's had the coolant pipe running under the manifold..If you are replacing it with a LS6 intake you will need the coolant pipe kit thru GM which plugs the rears and the new line will be in the front...
