Old skool this time, nova was brought to me with an engine pop/knock, ended up losing a few cam lobes and lifters, pulled the motor and refreshed with a roller cam and lifters and reinstalled, retuned the Holley sniper and she’s back to sounding healthy, also fixed/rewired up the electric fan to be controlled via the Holley instead of a switch
