its the performance ford COSWORTH edition its really good .if i were you,i would ring woodford garage motorsport 01803863958 and speak to simon(or any of the others ).thats what i did when i wanted a rebuild on mine.He didnt sell me stuff i didnt need.i just told him what spec i was looking for and he told me exactly what i should get.i got a good discount and it was there within 48 hrs.i cant go on about them enough, its a proper honest buisness who are not trying to rob you and just want to sort your car out for you.
