Change the 228 flywheel to a 215mm T4 (or 210mm or 200mm T4) and it bolts straight up to the gearbox - easy. The hard part is then working out how you are going to do the cooling system, and what carbs / injection to use - my 40 Weber-Alpha throttle bodies are on Wasserboxer IDF manifolds with the tops cut & rewelded & re-tapped to turn the throttle bodies around and fit the DHLA pattern. Fuel injection requires High pressure fuel pumps as well as a low pressure system, plus returns into the fuel tank. LOTS of wiring for the ECU. Throttle linkage is a much butchered T1 pull-style. Stock starter struggled to turn over the 10.5 compression engine, so that is now new. Etc, etc, etc...
Just work through it methodically and you'll get there. But you do need patience and to think laterally at times.
Expensive part for me was the custom made radiator in ally - £400...
