I recently put a edelbrock 4 barrel carb and intake on my 351M/400. I am having
trouble figuring out where the all the vaccum lines go that would help.

Well you should only have i think 3 that may hook up to the carb. You vaccum advance should hook to the single one in the front of the carb. Then your pcv onto the large port on the side of your carb. Your brake booster you can hook to your intake like factory or the back of the carb there is a large port for that. The what ever you do there you should just make sure you plug the other open ones on both the intake and carb. Hope this helps some.

I just had a real quick question about the vacuum lines for the blower motor and all, for the vent selector. I didn't even think about it at all when I did my 4bbl conversion. I ditched pretty much all of them except the vacuum advance, pcv, brake booster, and tranny modulator valve. I've still got some comming out of the firewall, that don't really go anywhere...um, anymore. Which one (s) are for the vents? Thanks
