Steve V Steve what kind of pin are you using?? It should be a spring roll pin. Some of the guys go up one size for more strength. I am running a stock MSD pin. I also have a HPHV
oil pump with 100 psi spring in the pump. Cold pressure is 135-137 at idle until motor warms up. Solid pins will not work. I will look and see if I can find a company that sell the correct one for you. Rick L.
