Need some help and advice...

I'm doing a little parts replacement, upgrades, and I'm quickly learning just how much height clearance I DON'T have. I've replaced the stock intake manifold with an edelbrock performer and since to utilize the stock carb I have to use an adapter plate. The plate raises the carb by 3/4" and new the manifold is already slightly taller than the original stocker. With a standard 3" air filter, the hood won't shut at all. For measurement purposes, I made a couple of 2" tall spacers to check for clearance, and the hood will close if I use a 2" tall filter element, but it closes very tightly, with the top of the air cleaner very obviously pressed tightly up against the hood liner. Anybody remove the hood liner? Any heat issues? Think it'll give me an extra inch?

I absolutely DO NOT want to replace the hood, just not an option. And it looks like I won't be able to fit any deeper of a drop base for the air cleaner without encountering different clearance issues.

Any suggestions would be welcomed and greatly appreciated!

Dave, My uncle had the same problem on his 76 when he switched to an Edelbrock intake and carb. He ended up getting a smaller air cleaner. I'll call him today and see if he will be home and I'll get a pic for you.

Henry removed his hood liner for the extra clearance. He had this done to the bottom of his hood.

same problem with my car, i have a BB hood (not a L88) with an edelbrock performer and carb. one of my buddies had a drop base 14 inch filter with a 2inch tall element that just seems to barely fit, but it does. i had to trim the stud that comes out of the carb so that it only shows about 2 more threads with the nut on it

what are your clearance problems with a bigger drop base?

I hate to say this, but you should have gotten the Edelbrock manifold with the "spreadbore" intake. Then you would not need an adapter.

Also, the stock hood liner had a round hole cut in it where the air cleaner sits. The aftermarket hood liners are solid and that round hole needs to be cut in it. There is a round inset in the backside of the hood that you can use as a guide with a razorblade.

Spent more money, problem solved (Thanks Raidmagic, you're getting good at coaxing funds from my wallet:nuts: )

Just decided (more, I agreed with Steve), at this point, I've spent enough, why not do it right. So, I went and picked up a new edelbrock carb. Now the adapter is not needed, plus the new carb will run better and I can eliminate a bunch of crap, EGR etc... so in the end it was a good call. I grabbed a lower profile 2" tall K&N style filter element, so I'll have enough clearance. It'll all get bolted up and put back together this week, gonna look great.

Thanks for the input gents:thumbsup:
