Howdy all. I recently purchased an 88 IROC TPI setup. Got the intake, a bunch of wires, a bucket of bolts and some small tubing. Ive looked around alot and have pretty much figured it out. However, there are some things I dont know. Could anyone please inform me of where these connectors go to? This is a pic from somewhere else. I need to know where the 2 hoses to the left of his hand go. Below it is another larger hose. where does that go to? the heater core? or is there a regulator or something before it goes to the heater? part numbers?

 

If it's a 305 you should have three hose lines,top one connects to a aluminum tube that goes to the valve cover I think it's for blowby,the one in the middle goes to the air canister it's a vacuum line,the one on the bottom goes to the heater core.Hope that helps you out.

 

Yup, the above is correct!
