Sorry, thread hijack not quite over...

Al, sorry, but that's no muscle car...it's just a big sucker, and you'd expect that output from that. My car (Celica GT4) is only 2 litres (with turbo), and puts out 155kw (210hp), 281 nm (207 ft lbs) torque, and does a max of 250kph, (~140mph), and the standing 0-100kph (60mph), also in 6.9 secs. Now, that's muscle, for an engine that size, and these engines can be tweaked up to over 200kw quite easily. I chose not to.
Ok, now thread hijack over...
