I recently picked up a 1995 cobra that the previous owner swapped the 302 for a 351. The engine is making a noise on the passenger side and I can’t narrow it down. The engine has a crane 1.7 roller rockers , gt40 intake, gt40x heads, and an e303 cam. I pulled the valve cover and didn’t see anything that jumped out at me. I also changed the exhaust gasket. Any help would be much appreciated.
