I'm gonna write:-
I may be wrong, please say if I am, but apart from the recessed block and the
bigger bearings on the crank, I thought the main(power increasing) difference
between the Mk 3 and MK IV engines were a hotter cam and bigger valves in the
MK 3 engine. I think early MK IV's had the bigger valves though. As I said
though, I ain't perfect(I once bought a Citroen), so I could be wrong.
