The compimentary video is pretty funny, too, with Clarkson doing some mad donuts:

I had to order a flywheel for my Series Land Rover Hybrid from RPI Engineering, the craftsmen of Clarkson's 5.2L SD1, 'cause I had a Rover 3.5 V-8 mated to a 5-speed normally used in a 4-cyl Rover. They were the only place in the world I could get the 9.5" 4 cyl. flywheel. With the Hybrid's 88" wheelbase, the 8-cyl. LT 77 couldn't be used. Long story..

The Rover SD-1 ('3500S' in the U.S., only offered to the U.S. in 1980 and was Road & Track's Car of the Year that year), had the same 3.5 liter as all of the Range Rovers, actually a derivative of the aluminum Buick 215 of the late '60's. Many surviving 3500S's in the U.S. have been converted to carb, as was mine with a Holley 4-barrel.

Speaking of federalized 80's bumpers, look what Rover had to do with the headlights. One-piece halogen headlights scared the federalis so much that Rover had design a dual headlamp set-up for the U.S. market. 'Totally screwed up the Ferrari Daytona looks.
