“Make your Jaguar the car it always could have been.” That might be a bit short because of the curve of one of the American companies that offers sets that can be fitted with such a noble predator cat with a Chevy Small block. In the USA this is not an unusual approach for people who do not have the money for Jaguar technology.
And Jaguars with defective blocks cost nothing in the US of A. Chevy small Block can be bought for about the same money.
The end result - if correctly implemented - can be completely convincing for people who are not so close to factory originality.
And the Dutch RDW? It is not difficult either.
