This forum is not for advertising but you may know that my company is successfully fitting 2.7 TDV6 Land Rover engines to LR Defenders. I think fitting them to 407 and later Bristols would be quite possible. Outputs : 240 bhp (179 kW) and 420 lbf.ft (569 Nm). SO plenty of torque, and easily over 100 mph, probably about 115 mph would be quite possible. Contact me off-line at
jond@jeengineering.co.uk if that is interesting.
