Anthony, the motor is also available with a SUPERCHARGER! The downside is that the block is iron, so it's no lightweight. The motor was engineered in the US to go into front wheel drive cars (fitted east-west) so it is quite compact, with the ancilliaries (alt, air-con, power steering pump) tucked in tightly aroung the motor. (Others note we use it north-south driving rear wheels) They also come with a german 5-speed gearbox (later models only - earlier models had a woeful Borg-Warner 5-speed), as an alternative to the big TH700 auto box.
I wonder how the all up weight compares with the Rootes 4cyl? The Vee format would mean the weight is kept well back. I suspect the trans tunnel would need to be 'Jensened' (ie hit with a Big Hammer ala Tiger).
Cheers, Paul.
