Check My Car Out - See Anything Out Of The Ordinary or Not Stock?

[lilbuddy]

I got my car about 9 months ago and I really know nothing about it. The guy I bought it from said the guy before him had the motor rebuilt. Currently there is 138k miles and all seems well. The block looks like it is painted blue which made me think at some point the motor was out. Do these come stock with a blue block?

Exhaust is an X-pipe no cats with I think a Magnaflow. I don't love the raspy crackling of it at times. I think there are 02 sensor deletes, you can see them in a pic.

Well here it is. I have no idea about any part of the engine from bolt ons to the air intake. He said he thinks it has a smaller pulley. Any input is appreciated.

Looks like it needs a new passenger side motor-mount.

Stock the blocks aren't blue. I do seem to see mil elimantors. Which, if you have no cats and no check engine light makes sense.

All pulleys look normal.

RX1Cobra is right: motor does seem to be leaning towards the passenger side.
