Ok first off i live in California and have to pass smog. Ok i have been wanting more carb for awhile now being i have the stock 20r carb. I have. Seriously been considering using a 22r carburetor and the lce adapter. Now i have all stock 20r head and bottom end and alll factory vacuum lines. And obviously the vacuum lines are totally different from 80 to 81-83. I was readin in my manual. But they only tell u specifically what vacuum line goes where for truck up to 80. And after that i couldn't find any more info in the manual in reference to hookin those vacuum lines to the 22r carb because they arent in detail because it seems the truck with 22r used some crazy band of vacuum lines. So that killed my search on how to hook up all the vacuum junk. And one have info on this? Just need info on doing a 22 r carb swap on 20r head and work with emissions stuff in my 80. Aka hook up all the vacuum lines. Sorry if any thing is hard to understand. I am doing all this from my DROID. Thanks
