You can see my system on my builder's site...

I have the TWM system.. I chromed the throttle bodies and gold plated the velocity stacks.....use a Electromotive Tec 3 controller, crank trigger system.
I think Wayne at verycoolparts.com has them. Hilborn makes them. There are may companies that will adapt your intake manifold for fuel injection also..
e-mail me if you have more questions...
