Weird thing done to 305, what cam is it?
Hey guys I'm new here. I have a chevy 305 that is a little "different", an I would like to figure out some things. I've taken it to a mechanic and he timed it and tuned it but is still getting 12.5mpg.
I took a video of the exhaust because I have no idea what cam it is and was hoping someone could guess? Is this why my mpg is terrible?

Again I bought the car and I have no idea what it has other than the motor or was rebuilt.
