Fantastic offer Crazy2287, really appreciate it, but I don't have anything ordered.  Enjoy your vacation!  I'm chatting with Kelford Cams in Christchurch right now and looks like he has something similar to the Crow speedway cams so I will see if that might be a solution.  Although I think I will be looking for an aussiespeed manifold in the nearish future.
To answer the older question, octane ratings here are 91 and 96.  I'd like to use 91 for cost, but in all reality, petrol is the cheapest thing about jetboating   I imagine the same thing is true for speedway.

LEGEND!! And that is what a good forum is all about, genuine blokes trying to help each other out. We are so lucky on this forum coz some other forums are all just negative crap and blokes having a pi$$ing competition to see who is better than the other ☹️

Flying into Queenstown on wednesday next week. If you get a cam before then I can bring it over for ya.

This is really helpful, thank you all for the feedback so far!  Talking to the manager at Hamilton Marine here in Christchurch he recommended staying around 9.5:1 compression ratio for longevity and tolerance to NZ fuel.  Does the Aussiespeed 2-barrel manifold make a noticeable difference over the stock one?
