What is the extra port next to the carb ports? and what can I do with it? Can I block that? What was the original purpose for this? [/url][/IMG]
Yup, that's what it is. Block it off, you don't need it, actually you'd be better off with a better intake that lacks that feature.
My stepson can upgrade the intake. And the heads for that matter. I'm just doing the bare minimum so he has a starting point. It's a 351W. Just fired it for the first time yesterday.
Yup, looks like its an EGR. I had to block it off because it leaked and made the engine run horrible anyway - MUCH better without it. What I originally did to get rid of it was make a small plate that bolted over it until i gout the funds to buy a new intake. Replacing it really isn't complicated. If I remember correctly, it's only 12 bolts, a water neck and a temperature sender. OH and a couple vacuum ports. Just make sure that you're not in CA and require a smog, and then you can buy a new one that doesn't have the EGR provisions. They have a whole bunch on Summit.
