If I was going to do it (and I am) I would have a frame builder make a frame with the same dimentions as the viper, but of chromoly tube. steel floorpan, aluminum rear panels. Integrated roll cage. Autoform carbon hood,facia,rockers and carbon quarters (yes, he makes them.. just call and ask). Roof section from a wrecked coupe, doors as well. Rear glass would be lexan, would have stock front windsheild.
Sparco seats, dash from a 96 RT/10 (no airbags),GTS door panels, Autoform interior panels (cut already), removable trans tunel for quick clutch changes and such.
Engine bay would consist of aluminum wheel wells, fluidyne rad and removal suports. Autoform vented cowl. 600hp NA V10, Gen2 block and heads. All plumed and ready to rock.
Aerodynamics would come in the form of a GTS-R vented hood (no NACA duct, just vents), front spliter and rear wing.
There you have it... a race car with street-pounding roots.
Man.. that pro-street influence is very evident in my designs eh? hehe
