Leon, you should call, I don't think anybody else is as deeply into Ford engines for er 'somewhat normal' human being prices.
I have 2000cc Pinto stuff laying all over and some nice interesting heads to go with them, wanna see a photo???
And you do want 2 liter for USA
And forget BDA-BDG waaaaaaaaaaaaaaaaaaaay pricey.
I have a big load of Cossie stuff ready to come over and could fling on some more junk, and I'm in the middle of a h class Capri build so I'm digging up the same sorta stuff you'll need.
Suggest Dana 30 rear axle, as big as Atlas but available here for cheep.
Found a starter shell??? Want LHD?
If you want something to start from scratch with you could go out and find yourself a Ford Fiesta (1980 era) and pull the engine from that. The fiestas had the "kent" engine I believe which is a 1.6 litre engine with a ton of performance parts available. Feel free to correct me if I am wrong, but I this is the same engine used in formula ford or something along that line. In any event BAT can supply you with a ton of go fas goodies and there are all sorts of modern swaps that can be done to the engine...ie cross flow heads and turbos etc.
