Default knock problem

the blower is now off the car and no more smoke present or oil spewing out. was running good for the last two days with no blower and im about a mile from home and the engine started to have a hard tick. not quite a lifter tick but somthing harder more solid. i checked the valvetrain alls good there. put back together start it up and knock still there, start pulling plug wires and noise doesnt go away. what could this be?

well when you took off the blower, did you remove everything you put on for the blower?

The tune

Big Injectors, etc all that,

its not an exhaust leak for sure, and it wouldnt be a rod knock because it didnt go away when i pulled the plug wires from the cylinders.
