and illegal... for the tyres protruding beyond the guards and also the air filter out of the bonnet.
As for superchargers, here goes:
Those "roots" type blowers' numbers are just relating to the size of the diesel engine they originally came off (like a bulldozer etc). So a 4/71 was off a 4cylinder, 6/71 off a 6cylinder and 8/71 you guessed it, off a V8 diesel. So in a nutshell its the size of the blower.
Most common is the 6/71. It's the big one on show cars, hot rods and drag cars that comes well out of the bonnet with two carbies or injection ontop.
The 8/71 is really only seen on very serious drag cars and specially made blowers go up to 14/71 like in Wild Bunch, funny cars and top fuellers (although alot are using screw type blowers now like PSI).
The 4/71 usually fits under the bonnet and only has one carbie. This is whats on the vette.
Edelbrock (as an example) refined the 4/71 and called it a "low blow" and with teflon seals, single or twin carbies and factory high polish they look and perform really well and with a small scoop can fit legally under your bonnet.
Then there are small screw types like Paxton and of course centrifugal types- the ones usually fitted to later EFI engines like on commodores, falcons, and of course C4 + C5 corvettes. They are basically a turbo driven by a fan belt rather than exhaust. Instead of a linear power curve with boost right off the line like the others, these give a similar power curve as a turbo- not much off the line but ever increasing surge of power as she revs out.
Now that was a spiel and a half ;laugh
So with that vette, if you can't see two foot of supercharger and carbies out the bonnet then she 'aint no 6/71!:}
