Does anyone have vacuum and smog charts and requirements for smog on the 454 motor on this unit. I got it and it looks like the motor has been chaged and I need to add a few items to try to smo. I believe it has to have the same smog as a commercial vehicle( I can't fing any diagrams) and when smogged they use the 2 speed idle test on the ground to test .help.
thanks steve
