wbute answered the diff thing.

The rods are the same spec only as a 1973 (150 list) XU1, the rest of XU1 are the same crank and rods as a normal red 202. The blue/black 202 crankshaft is very different to a red 202 crank.

The actual concept or effective cc of the turbo or blown 202 isn't the rego issue with a WB. It is the emissions or pollution equipment problem, ie compliance with ADR27A, 27B or 27C depending what compliance the WB chassis you have is (AWB, BWB, CWB etc). The reason the stock EFI 304/350 or the blown V6 easily comply is they are a later emissions requirement and automatically comply. The stroked 304 (which will be a 330-ish ci or 350ci engine) will probably have the same issues unless you dress it up with all original WB V8 pollution equipment. The easiest way around it all is to change out the chassis for a HQ or HJ one!
