The saying is "Horsepower is in the heads" To get an honest 380 hp, you will need to spend a few $ on the heads. Larger valves and port work. But, it is pretty easily done. The only issue will be manners and streetability. Keep the compression high to keep the low end, and you will need to mix the gas. Lower cr and the bottom end might be a little soft. Good heads, cr around 10.5, a cam in the 225-230 @ .050 range, RPM intake and good headers and exhaust, and you ought to see 375. IMO, it will be tough to ,make much over 400 and still be streetable. But remember, the # doesn't mean everything. You can have 300 hp, lots of torque, and a low-mid 13 second car that is a blast to drive. Some of those Jetways had a switch pitch converter, somebody who knows will chime in, hopefully.
