Ping noise still here, did my mechanic put the wrong replacement cam in?
Would the fact that the cam that cam out of the car was a SBC HYD HMV-278-2 and the one put in is a COMP CAMS 268H (part#12-210-2 [49]) and the RPM range, the rocker arm ratio(1.5,1.52), and pretty much all the numbers seem to be off a little.. Think maybe that might have something to do with the pinging? I found out the rest of the problem in the thread below is detonation issue and I am upgrading the fuel pump and getting larger injectors, but this pinging noise is bothering me.
