Thanks, Andy for the welcome and such a quick response. Common sense tells me to go the single donor route as far as I can but I have heard that the Zetec engine is much better. I have no experience of it but I do remember the Pinto being a bit weighty and designed in the late 17th century.
It made the 2b shift though, it had twin 45's and a fast race cam, very nippy.
Can anyone tell me which engines had which gearbox fitted? I have read here that the standard design needs tobe changed a lot if an MT75 is used but I am unsure as to which Sierras used the type 9.
Best,
Enoch
