What is the 'glitch' with the Rover(Buick) engine? Size, originality, unreliability, parts availability?
OK, Everyone would (probably!!) rather have a 289 sat in there, but on our side of the pond, that (or even a 302) is a lot harder to come by.
In it`s defense, and bearing in mind that our Petrol (Gas) costs five and a half bucks per gallon(imperial...of course!), You could quite easily expect to get 30+ mpg on a run and 15+ mpg when giving it some boot.
We laugh in the face of the thirsty 427 s/o brigade and their 6-12 mpg.
