Aluminum Intake Manifold ??
I am thinking about buying and installing an aluminum intake manifold on my 77. I am wondering if these intake manifolds will raise the height of my carb and breather and cause issues with clearance of the hood? Thanks

Thanks for the input guys. The reason I was thinking about it was for appearance more than anything. I am working to clean up my engine bay and have removed the carb, valve covers and coolant hoses etc., with the thoughts of cleaning up the original intake and putting on a fresh coat of GM blue paint. A buddy of mine suggested that since I have everything out of the way, I might think about putting on an aluminum intake to spruce the looks up a bit.
As I have replaced things, I have replaced them with chrome i.e., water pump, thermostate cover.neck, alternator etc. Most likely I will just stick with my original plan and get the original cleaned up and put on the fresh coat of paint. I think just by cleaning it up and painting it will be a vast improvement on the looks.

If you're using the stock air cleaner, I'm not sure how a smaller filter element would help, on the 77 anyhow. The 75 looks like a smaller filter element would do the trick.
Also, I'm using the ZZ4 intake on my setup - they come straight from GM and are a different casting from the Edelbrock 3701, although similar in feature. I find it fits the stock accessories a lot better than the Edelbrock did or the Weiand 7525 I have in spare.
PN is 10185063. It's probably the closest thing you'll find to an L-82 aluminum intake as a new factory part.

I run an Edelbrock Performer EPS with a Holley 4160 (80457s). Carb sits on a taller gasket to provide access for the PCV hose. I have no clearance issues with a drop base air cleaner.

The amount of hp they might give a stock engine would be within the dyno machine's error range.

I agree totally on a stock motor you aren't going to see anything you need a complete package, heads, cam, carb, headers etc. I picked up an extra Edelbrock Performer for my 66 El Camino from e bay for 85 bucks and it looks like new.
