Modern 1974 IROC clone, this was started on a Grand Prix White L-908 1974 911, and fitted with a 964 based 3.8L engine. 
The engine is managed by MoTec and features our new billet EFI "Slide Valve" manifolds! 
We have fitted the car with a RUF 6 speed gearbox that is based on a G-50/50 transmission. The result was a super lightweight 380 hp street/track monster.
