My Gaffrig arrestors are 2"X10", but the effective screen height is 1 1/2".
Fred, I'm sure there's a way to do it.

I'm going to see how many layers mine have in them and "adjust" them accordingly.....Fred

Here's what I know about the engines;
509 CID GenV blocks, JE flat-top pistons, Manley rods, forged cranks, Fluidampers, Merlin rectangular-port heads, Isky 8005A springs, Crane Gold 1.7:1 rocker arms, custom-ground flat-tappet hydraulic cams (something less than .600 lift), B&M 250 blowers @5 lbs boost, 1050 Holleys, Thunderbolt ignition with V-6 modules, 34 degrees total advance. I'm still waiting for the dyno tables as the dyno shop is waiting for their new printer/copier/fax machine. I freshened up the heads on both engines with new valves, guides, springs and exhaust seats early this season.
