Thin Lizzy 37 Report post Posted April 30, 2017 Hi All, Does anyone please know if it's possible to fit a 3" high air cleaner under a Mach 1 hood? My 69 has an Edelbrock 1406 fitted with an ugly 10" x 2 1/4" Edelbrock cleaner. I was wondering if I fitted a nicer looking Edelbrock Elite 14" X 3" cleaner, would it fit under the hood scoop and would there be any detrimental effect to the airflow around the hood scoop? Thanks for any help you can give. Quote Share this post Link to post Share on other sites

Pull the hood back up and measure the clay for home much room you have. Matt 1 Thin Lizzy reacted to this Quote Share this post Link to post Share on other sites

1969_Mach1 333 Report post Posted May 1, 2017 You need a drop base air cleaner. You can buy a K&N 14" diameter drop base by itself. They offer 7/8" and 1-1/4" drop bases. Your electric choke on the Edelbrock carb might interfere with the 1-1/4" drop base. Your fuel line might also interfere with a drop base. I think Edelbrock makes a fuel line for the carb that drops down for more air cleaner clearance. With a Holley carb, the 14" diameter combination I have found that provides the most hood clearance is a K&N 1-1/4" drop base, 3" tall filter, and Moroso lid. You can also simply get a 14" Moroso air cleaner assembly with a drop base and 3" tall filter. These have a 1" drop base. Moroso also makes a specific carb to air cleaner gasket to fit their base. A regular gasket will work but theirs seals a little better. Whatever combination you try make sure it is from somewhere that has good return policies. As you know there are hood clearance issues. But also the choke on your Edelbrock carb can cause fitment issues with drop bases, and sometimes a 14" diameter air cleaner will contact the distributor cap. Lastly, with drop base air cleaners also check the clearance between the air cleaner lid and top of choke on the carb. 1 Thin Lizzy reacted to this Quote Share this post Link to post Share on other sites

barnett468 418 Report post Posted May 2, 2017 You can also use Play Dough or Silly Putty but put anything you use into a plastic bag or loosely wrap it in plastic food wrap so it doesn't stick to anything. Keep in mind that if you don't want to adversely affect performance, you need at least around 1 1/2" (37 mm) of clearance from the top of the carb to the bottom of the air cleaner and 2" (50 mm) would be better, but this clearance is sometimes less if you use a drop down air cleaner on a carburetor that has a choke on it because the choke gets close the the bottom of the lid. 1 Thin Lizzy reacted to this Quote Share this post Link to post Share on other sites

Thin Lizzy 37 Report post Posted May 12, 2017 I had another idea. Is it ok to fit my original aircleaner to the Edelbrock like I've done here? Will less air go to the carb than than the other air cleaner due to the narrow snorkel inlet? Quote Share this post Link to post Share on other sites
