Thanks for all the replies, and info on the hurricane intake. I'm not looking at any other intake other than the Hurricane or the RPM because I have both. Sounds like the RPM will be the better choice and I already have a drop base air cleaner ready to go. Here are the specifics on the car:
1968 Firebird 400 block with forged stroker crank, bored .030 over Cam specs are: 220/232 duration at .050, 485/510 lift and 110 lobe separation Stock rods with ARP hardware Forged pistons Stock 6X heads Quadrajet Carb Dougs Long tube headers, X-pipe with Flowmasters Tremec 5 speed 3.42 rear gears Weekend cruiser mostly on the street
