blacktop head over silvertop head, so to be legal it needs a cert for that too.
All depends how legal you want to be, but at end of the day.

I didn't mention safety ... I mentioned insurance companies looking for a way to not pay you.

A vehicle is not required to be certified to the Low Volume Vehicle Code provided that the safe performance tof the vehicle is not compromised, where the only modifications to the vehicle are those to the engine originally fitted to the vehicle by the vehicle manufacturer, that result in an increase of no more than 20% in an engine power output from the original vehicle manufacturers specifications

- Is of the same or less capacity or power output; and
- Is of the same configuration; and
- the fuel type is not changed from petrol to diesel or vice-versa; and
- has the same type of fuel induction system;
- has the same weight, location and centre of gravity; and
- Is of the same design and casting family of cylinder block and cylinder head(s)

but the one that holds the answer is in fact this section:Section 4.3 wrote:Engine conversions that do not require certification

Following that, because the blacktop is rated at higher power output, you require certification for your car to be legal to the letter of the written law.
So how much you wanna try weasel your way around the semantics of it all is up to you.
