1983 Sierra XR8 Wannabe
We've got a 1983 Sierra 2.3 V6, C3 gearbox is on its way out, and the engine will probably follow it soon in sympathy. We have also got a spare 289 V8 with C4 gearbox. The idea is to put the 289 into the Sierra, I know that there were about 250 V8 Sierra's [XR8's] made here in .za, for Ford Motorsport in about 1982 odd, but from what I have seen of them, most seem to have 302's in. What I need to know is if anyone has done this type of transplant, there is no real difference between the 302 and 289 so fitting in is not a problem, more the engine mountings, the 2.3 V6 does not have the same mountings at the 3.0 V6, what is the best way to work around this.
And would we have to change the rear diff.?
