MKIII Cortina suspension question

[Rossouw]

Hi Guys,

I swopped the original 1.6 engine in my 1976 Cortina mkIII with a 3.0 V6 Essex. The car was sitting a bit low in the front so I changed coil springs.

My question is: Should the front suspension and brakes be upgraded due to the heavier engine?

Any advice would be appreciated.
