[TR] [6pack] Lucas PI

[Paul Tegler]

Granted it's not the 2.5L, (a GT6 2L) but I (and a couple others here as 
well) have F.I. triumph 6 cyls than run great!
Even with a trailer in tow,?? 31-35 mpg, is my norm ...with my normal 
heavy footed driving style. (hard not to have fun).
No,,,not Lucas PI (on mine) but power numbers are well above anything 
Triumph ever spec'ed.
