PC-CHARGER OP super stock Joined: Jun 2006 Posts: 916 MB,CAN	Finalizing the EFI setup on my current project and I now have to figure out an air intake/air filter setup. Using the FAST 1250CFM throttle body and the throttle lever is quite tall and will hit a normal air cleaner so the plan is to use a 90 degree hat with piping up to the front of the rad cradle and a cone style filter. I want to keep the height down as much as possible and I've found a hat that is only 3" tall but it also only has a three inch inlet. Is this big enough to feed a 500 inch engine or do I keep looking for one with a four inch outlet or????

It's common to cut the lever down to clear the underside of an air cleaner. A 3" inlet is pretty small, but it's the HP that would determine that. I made a custom base for a customer that cleared the linkage and allowed for a full circular 4" air cleaner.

Check your gas pedal movement and see what ratio the arm needs to be before you go cutting anything
