I have a Edelbrock preformer intake and Edelbrock Avenager 600 CFM carb. I know I need a drop base Airfilter but I'm not sure what one. Jegs' tech people wern't much help. I just don't want to but the wrong one. thanks-Matt.

I'm running a 14x3 K&N element with a Performer RPM intake (which is higher than a plain Performer), and running a 1.5" drop base without any clearance issues on a Camaro.

Looks like you are running a 305 which means you could stick with the stock element (12"x2.5"), and run a 0.5" drop base without any problems. If you want to go with a 14x3 element, then a 1" drop base would be safer.

Thanks man, I bought the car with a 650 Holley dp. It was filled up with rust from the bad fuel tank. I replaced the tank, manifold(it was stock), and carb(new fuel lines, filter...ect). Not i just have to finish what i started. I have also have a few problems with getting the correct brackets for this combo but i think i have solved that.

by any chance do u have a part number? i have the same issue. I have a vortec performer rpm intake edelbrock carb and no hood clearence I've heard that too much of a drop in the base will interfere with the carb any ideas? my carb is manual choke by the way

Just go to auto zone and buy the standard drop base open element and install it right in the parking lot...if it touches any linkage they sell a spacer kit to fix that issue.

Edelbrock calls their carbs "Performer". Holley makes a line called "Street Avenger", but no 600 CFM. What carb do you have exactly?

sounds good i'll give that a shot thanx :thumbsup

Forgot about that...if you have a Edelbrock Performer carb, there might be clearance issues for the fuel inlet on the smaller 12" dia. drop base, but should be fine with the 14" unit.

FYI - I'm running a pre-1974 modified QJet carb without any clearance issues with the 1.5" drop base.

i have a 14" i believe I"m pretty sure my fliter is 14" but not 100% sure but i'll give that a shot thanx
