I have an 85 k5 that I yanked the 305 out of and put in a 350 from late 70s pick up I'm using the brand new carb off the 305 and need to know what vacum lines to plug since the 350 doesn't have all the emissions crap on it . Thanks for any input I can get

By the way the carb is a quadrajet 4bbl

 

It really depends on what you have there to hook up and what you think you can do away with. How many lines are there and what are they running to?

 

Thanks any way but I did a little tinkerin around and she runs like a raped ape what a relief

 

Alrighty then. Glad you got it fixed up!
