go back to the start and read. James never said it was a 406. James told you on the phone that "the intake and carb had been changed and and that it did not look like the engine had been changed but I did not know" That means you need to look for your self. I told you on the phone I did not like the van and I did not mess with it. You only talked to me 1 time a total of 3 min before you came to my house.
