3.9 litres in a GTO TT Plug and play

It's getting closer,, the heads haven't been rebuilt, there's still a few bits missing but getting there. Then after it there's the plug and play 6G75 into a GTO TT, that's getting closer too. 4.4 litres if I can get the subaru pistons to fit. They're 99.5 mm, I might need to offset bore it a bit to clear the oil feeds. Then some blue junk in the background. My old junk from '88. How to fix a Ford? Build a Mitsubishi.
