Thanks for the clarification. I stand corrected.

Vance, as this list and triumphs@autox.team.net is widely populated by
enthusiasts who 'feed' on what the factory did - and why. May I (with
respect) correct your claim?

The key problem with all the PI cars (TR5 and 6, together with the
2500PI
saloons) was oiling of the plugs in heavy traffic. Even the 132bhp
saloon
car suffered these difficulties and it was only when Lucas refused to
undertake any further development work with the mechanical fuel metering
unit to reduce these general difficulties, that the TR6PI saw a 'pwer
reduction' to 125bhp from 150bhp. It didn't make all that much
difference
from a driving perspective because the torque values weren't affected -
but
the cam was substantially modified.
