Radiator help
LS6427, how is one that that has two one inch cores no better than a radiator with a single one inch core?
If you want to do the best upgrade you can do to your cooling system, that will give you results and you will run cooler.....get an LT1 radiator. Its a direct replacement, same coolant level sensor port...its 100% identical in every way to the LS1 radiator..except an extra port that you cap off and it has 30% more cooling capacity.
Cap that extra port off and your done. Its identical to the LS1 as far as fitment.
