Alright everyone, So for the last couple of weeks I've been trying to solve my pinging issue on my El Camino. The pinging starts at about 1800rpm when I'm accelerating just beyond cruising speed, and it happens only when the car is up to temp. I'm running a 454 bbc 9:5:1, cleaned up iron chevy heads with a Wieand stealth plane manifold, Edelbrock 1411, and for a cam I've got an Isky #396286 with 224 degrees on the intake and exhaust at .050" lift. The trans is a turbo400 with a Hughes 2500 stall converter. The carb is jetted two stages richer on the edelbrock 1407 chart with 116 main jet with .070 x .047 rods and pink springs secondaries are stock with 107 jet. I've got a Accel HEI distributor with adjustable vacuum advance turned all the way in to provide zero advance right now. Initial timing is at 12 degrees with mechanical all in at 3000rpm at 32 degrees. Plugs are r43xls delco's set a .045 gap .So this stuff is all new to me and I've been learning on this car. But it's my dd so I'm worried about the pinging. Any help is always appreciated.
