In fricking Mexico or canada. Most of our "American cars" parts are imported from somewhere.. You have no clue where 90% of the crap is made at nowadays. The politicians screwed us royaly. I buy what my budget dictates. I have procomps on my 383.. Havent driven the the with the new motor yet but most "American" made stuff is waaaaaay overpriced for what it is.. I will buy american when the price is right. I have heard a lot of nice things about the procomps. American jobs have been created fixing some things on the heads
