Picked up a set of 062 Vortecs and matching GMPP aluminum manifold today from a Craigslist seller.  Everything looks to be in pretty good shape (although the heads will get a valve job, re-spring, screw-in studs, etc) and I'm pretty excited about the setup.  My plan was to use the stock air cleaner ass'y or similar, but I do have some concerns about clearance with the stock hood.  I've read a few posts on this site and others about clearance problems and dropped-base air cleaners, but after some measuring today I think there's a chance I'll be OK.  The manifold I bought is similar to this one, but I think mine is an older version: daveo762011-04-30 21:40:32

I can speak only of my experience with the '78 L82 I used to own.  This was with stock heads, not Vortec.  I installed a Performer intake and it worked fine.  It was slightly higher and pushed the stock air cleaner into the hood insulation a bit, but no big deal.  The Performer also places the carburetor slight further back, closer to the distributor.  No problems, though, but one of the cold air duct hoses was slightly stretched to connect.  Again...no big deal.

Excellent, pretty much what I was thinking would be the case.  Thanks!

Yep, I'm thinking a little modeling clay might be in order!

[QUOTE=daveo76]Yep, I'm thinking a little modeling clay might be in order!  [/QUOTE] That's what I did. Located it at several areas around the air filter housing. I also went to a button head screw in place of the wing nut with threaded rod.

So which manifold are you running, Suncountry?   And with the stock air cleaner?

I copied this from an earlier post I did on this subject.

 

 

I also add I have a 1/2" carb spacer so the accelerator pump clears the manifold. I am using a button head screw to hold the air cleaner on. Here is a picture of the setup

The filter in the one picture came with the assembly with I changed out for the K&N. I also did not use the bow-tie wing nut to hold the filter down.

We are running into the same problem

What carb and manifold is that, Stingray Don?  That carb doesn't look familiar.....

The carb is an old Webber 9635 650 CFM, It still needs a little work but seems to be a good carb
