Gentlemen,

I am thinking about replacing my Performer intake with a Performer RPM Q-Jet. I am planing on keeping the Lars' modded Q-Jet for now. My question is, will the 1970 LT-1 air cleaner base (see below), fit a Q-Jet?


This is on the '75 with a stock hood.

Yes, I have the same drop base that I used on my stock Q-jet and now on my Holley 670 Avenger. I have a 72, the 75 hood is higher than a 72. I just installed a Proffessional Products square bore 4.65" high intake (Performer RPM is 5.25" at the highest point) with the Holley along with the drop base air cleaner, a 3" open element. I have about 1/4" clearance left. This is measured from the highers point on the air cleaner lid to the hood. Best of luck. Mark

What is the drop on that air cleaner, and where can I get one?

Zip Products has them...

you can get a drop base air cleaner at autozone for about $35.00. Holley brand gives you about 1 1/2 inch drop.

I just completed my intake and can vouch for the Holley drop base too. I have a stock 76 L82 and just installed the Performer RPM intake, a 670 cfm holley street avenger, and a 3" K&N filter in the holley drop base filter kit yesterday. I'm certain Holley makes the Summit #sum-239433 too which is $35 as well. It just has a plain lid and claims a 1 3/16" drop. I compared both and the bases are identical.


I have to addmit, once I screwed the nut on the filter, I didn't think the hood would close without damage. I figured I'd have to go get the 2" filter. I set the hood down gently (no 10" drop yet ) and push it at the corner until it latched and the hood never hit the nut.

I'm picking up some clay today to see the actual clearance. Since I have steel mounts I would think about 1/4 to 1/2" clearance should be enough. BTW I have no hood mat or retainer stud either.

Maybe this will help your situation..
