jhv48 Jim ERa sells the kit with #10 lines. Can get a kit with #12 lines if wanted. Others have said to get max protection from your
oil, it has to be in a certain temp range. Too cold is about as bad as too hot. Mine runs in the 195-215F range. This is with a SW gauge and not sure how correct the reading is. Other things are I run a HPHV
oil pump with 35-40 psi idle hot and 75-85 at 2,000 rpms. We can skip the whys of this. If you want to use the cooler and look into a thermostat. The other thing is this There is no cooler fan, so only the air that goes through the cooler is cooling the
oil.At a stop unless your radiator fan is running you have dead air flow. Best thing may be to take a trip and cruise and whatever speed you like and check the oil temp. Tell us what you have. A hotter day would be better. Have to remember that all fittings on the lines are like funnels. We never talked about your motor. What power numbers, compression and camshaft design, solids, hydro's or rollers? It might just be better to goto high flow fittings and change all the connectors and leave the lines in place. The swap is easy but messy. Have to remember bigger is not better,
