I got the Vic Jr. for my 408 LS3 heads with Fast 4150 T/b no hood clearance problems I will be using drop base:Spectre Part # : 98323
Application:
Cowl Hood Design With Tray - Extraflow™ 14" X 3" Red HPR™ Filter
Features:
• Universal open top airbox designed for cars and trucks with cowl style hoods. Seals to the underside of the hood to isolate the filter from the hot underhood air, drawing cool outside air from the base of the windshield
• Overall air cleaner height is 4.2"
• Powder coated drop base lowers the air cleaner 1.7" for an overall 2.5" from the carburetor flange to the airbox sealing edge

You better be spinning your motor pretty high or the loss of low end will bite you in the ***. For certain applications it is kick *** and makes significant gains over a FAST. But you need a high shift recovery and high stalled converter.
Will be running one on my N/A 454 LSX but its got a 4.6k stall and will be reving a little over 7K.

HP peak climbed 1000rpm,TQ peak climed 1300rpm, power increased by 25hp over 6000rpm, car picked up 3mph and a tenth in much worse weather in the 1/8, turning a slow lazy 60 foot (1.69 vs 1.5s previous). With a converter change, it will go much faster (pending).
Def a good change, but you'll have to turn 7k+ to make it work.

I'm lookin over Tony Mamo's 750hp 454 and wondering how much more hp it would make, because as he said you can't put that much torque down so it would be better to make more power up top.He's using a Mamofied Fast intake. Just think wat a Mamofied Holley Ram intake could do.
HKE did a 5.3 for me with high CR and big cam and I used the Holley high ram intake and I made 499.6 RWHP to the wheels. This was one 2004 Silverado truck with a 5800 stall and 5.38's it ran a 11.0 @ 123 MPH. I would shift this little monster at 8300.
