Hi Ben,
I can't give you a generic price for this unit as all of these are different in spec. such as the injector size and make. You can have Boesch or another type that is much cheaper. also the intire throttle linkage is designed for this setup. The major components come from DC&O in Australia. The package that I got included all the plumbing and two racing fuel pumps with filters and wiring intergrated into my main harness. It also has all the trumpet stacks and all the sensors and throttle cable. For this I paid
$4.5K. To me this is a bargain because of all the components are there and it's ready to go.
From what I understand, it is available for the 351w as well. I don't know about other applications.
