I seem to recall something about them using two convertors to feed the one Vortex mixer on the 500HP big block. I can't find the magazine it was in now so I'm not sure. It was about 2 years ago in a Ford Performance magazine. A yellow XA or XB coupe. Of course the flow potential of this mixer is also dependent on the carby it's sitting on top of.
I'll get a quote from Gas Research anyway.
The Sprintgas Vortex rig is going to cost me $2,000 for the complete install including the tank, convertor, mixer and all the required fittings as well as setup.
For the Impco rig they want $2,500.
So if Gas Research is in that kind of ballpark then I guess I should consider it.
What would be really nice is one of the Sprintgas Electronic Gas Injection rigs. But that's more like $4,000 and a bugger to convert a Clevo cause they never had EFI standard so inlet manifolds have to be customised to do it. Windsor fuel rails fit though.
There are two types of fools.
The first, who thinks that because it is old, it is good
And the second, who thinks that because it is new, it is better.
