The XK Falcon built to take a straight six had a 70cm wide engine bay (shock tower top to tower top), over the generational changes of Falcon the engines bays expanded, but it wasn't until the EA series the engine bays exceeded 80cm in width. 80cm being the width of the Boss 5.4L motors in the XR8.
Question: "I want to put 427 dark block in my XB coupe but it won't fit, I want to run 17x8 globe bathurst replica mags, and adjust the ride height so the tyre sits just right, so I can't use a mustang2 style front clip in, what can i do?"
Answer: The Cammer shock tower notching kit will allow you to fit a big block, stock Barra turbo, or modular V8 from an XR8, the RRS coil overs will allow height, ride, and camber adjustment.
Gives you up to 10.5"of Engine Bay space.
Standard Notching Kit
Modular V8 Notching Kit
Notching Kits are optional the RRS coil over suspension kits and rack and pinion steering systems are bolt in and do not require any modification to your classic ford.
RRS Shock Tower Notching Kit - this application is OPTIONAL
The RRS notching kit will increase the distance between your shock towers by up to11 inches allowing ample space for that mammoth 426 or 429 big block as well as turbo small block and hard to fit header applications. The best part of all is that you retain the integrity (strength) of your shock towers. Giving you all the room you need to install that monster Ford V8 in that engine bay. Then look no further than the combination of the RRS Strut and Brake Kits and the RRS Shock Tower Notching Kit.
