I am wanting to remove the smog pump and all unnecessary emissions stuff from my 84 454 c30. Can anybody share a vacuum diagram for the early models? Input welcomed.
Hey folks, new to this forum. I have a 84 C30 with a 454. I've had a few of these squarebody trucks in my 48 years. I always seem to gravitate towards them. Haven't ever had one with a big block though. Gonna be looking for a little technical advice. Thanks
