Hello all

,
I'm new to this forum and rather naive to this specific topic so go easy.
OK, the story is, I'm putting a 429 into an XB hardtop(complete groundup rebuild of the whole deal), and a friend has told me he has a contact in Japan that may be able to get me a supercharger to suit this engine real cheap. Over there they only keep their vehicles for around 5000-6000 klms because they're so cheap, so said blower will be second-hand, but in reasonable knick(hopefully!?!). Ive chosen the 429 over the 460 simply because it is a little more unique in Australia and it has a slightly better rev range.
Questions:
I'm going to invest in the Edelbrock Performer RPM heads(CJ ports), which come in two sizes, 75cc and 95cc chambers. As I understand a low compression ratio is appropriate for supercharging, so the 95cc heads would be the obvious choice. But if I decide not to use the supercharger then I am left with a really expensive set of heads and low compression

. Can you open up the chambers on the 75cc heads easily if I do use the S/C. What do you reckon folks?
What is the prefered system for this application(centrifugal, screwtype....)? The car is mainly going to be a show peice, but it will be registered and it will be driven to shows and local strips.
If the blower type that I use requires that I have to cut open the bonnet then does anyone know what the legalities are for equipment (say a bloody big bird catcher) sticking out of the bonnet in NSW? I,ve heard lots of different ideas on the rules but no definites.
Cheers people, I look forward to any comments.
I'm going up the pub while you all come up with some answers
