How's it going MC. In need of a Lil help with my ride. I recently bought a 1988 MC Ls. This Mc's engine was replaced from the stock 305 to 350. I did some research and I'm able to have the swap. (By the way I live in California) emmisions regulations suck here. I'm having trouble with the vacuum routing and sensors. Does some one have some detailed pics of the emissions, vacuum routing or any thing that might help me get it running and pass smog legit? Thanks in advance!!!

 

Hopefully this diagram should help you out!

 

Welcome to the site. Good luck passing anything in california Ive heard its pretty tough.

 

Thanks for the welcoming lougreen03. I found out about a loophole where I can smog it when I register the car and not worry about it ever smogging it again.

 

It's the same diagram I got but I can't seem to find or understand what the EFE valve is on my car. I've looked it up and have not found it
