If the engine used, in a GT configuration, came with ram-air/hood scoop, yes it's permited. If not, then no. Case in point. 1998 Firebird with a 1997 LS-1 engine in GT = hood scoop allowed. 1998 Firebird with a 1969 Chevy 350/295 = scoop must be blocked off, or flat hood used. As ss3011 said, the weight break for GT/AA is 8 pounds, same as SS/EA. 4,170 pound GT/AA car, using a Race Hemi @ 500 HP. There are better engine options out there to use, I'd think. The 1970 Dodge 383 looks good, 330 factory, but NHRA rated at 304. Staci Smith has one in a '93 Daytona, runs 9.60's. Talk to Jeff Tueton, I think he and Sid Bonnecarrere use a 383 or smaller motor in SS/GT in a '68 Cuda, with the factory SS/AH-type hood scoop (I think it's a 360 in GT/FA).
