Factory Five Roadster first start. I've been building this car for about a year and a half. This is the first crank and start! -- Engine is a Roush 331 SRXE crate engine. That's basically a 302 (5.0L) Ford small block, stroked to 331 cubic inches (5.4L). It's also fuel injected and delivers 357HP and 368 lb-ft of torque. Not too shabby for a 2000lb car.
