alright from the get go of my project of swapping out a 305 to 355 I've been around guys that are more used to Carburators, my question is can or does anybody have a diagram I can follow for the Vacuem lines that are in the front of a TBI of a 91 RS Camaro that the PCV valve is located on the front of the passenger side and the ventilation tube is located on the back side of the driver side valve cover. I've checked with a chevy dealer with my vin# for accuracy on the valves. I have figured it probably doesn't make any difference on actual location of these cause as long as there is vacuem go to the pcv valve it will automaticly circulate the air through the crankcase area. Is it a Map sensor that goes towards the back of the TBI or is it a MAF sensor and where is this located and what is a description of it that I would be looking for? I've figured the bigger vacuem in the front goes to the pcv valve, how about the other ones? Thanks

 

Here's the diagram again. Is there a question this doesn't answer?

If that drawing didn't help you here is a thread with pictures of TBI units with notes to the ports.
