Need a Mopar guru: 273 part-throttle ping driving me crazy!

it's probably an exhaust leak at the manifold.
i seriously doubt that 4 gallons of 100 octane added to 10 gallons of 91 put on a car with stock compression ratio was really fixing anything. just sayin

I can tell you that there was a SIGNIFICANT reduction in the amount of pinging when I did that. However, I also changed brands of gasoline at that time (Unocal) so maybe it was the brand of gas that did it more than the octane...

i'm speakin from experience about exhaust leaks. i would bet that is your ping you are noticing. maybe some lifter noise along with.

probably wasnt high end gaskets i'm betting.

get a set of percy's exhaust gaskets.

i'd also recommend setting the valve lash. if he put stamped rockers (non adjustable) then skip that step.

Do I have to pull the valve covers off to determine if I have stamped non-adjustable rockers or will I be able to look through the breather/cap hole?
