I'm helping a buddy piece together all of the plumbing on a new build and I'm looking for feedback on what size plumbing people have used on similar builds and how its working. He's got a stock LS LQ4 6.0 that will someday see a mild cam. The radiator is front mounted and the hoses will be relatively short. The plan is to use weld AN fittings on the LS pump and radiator. I suggested to use -16 everywhere because the price and selection of fittings is better than it is for -20. Thoughts?
