After putting some run time and street miles, I changed the oil. It came out looking great. Moving from Castrol 10W-30 to Castrol 5W-20 to see if it will lower the start up oil pressure (now 40 pounds at idle) I changed the water restrictor from 3/4 to 5/8 and it will get to 160 on the guage now. With the 3/4 restrictor it would only get up to 120 in the heat. Besides having some guage issues the only problem I have now is that it lays black marks.
