Gary,
I recall that you are interested in EFI for the 514. I just spoke with TWM (check their site), and they will have their Weber EFI system available next month! This is the system with 58mm throttle bodies (biggest on the planet) and the fuel rail and injectors "hidden" under the massive throttle bodies due to the 10 degree cant in the manifold. A warning - they've been saying "next month" for 6 months now....one can only hope
Also thought you'd like to know that I installed the accusump pre-oiler with no problem. I'm hoping this will extend the life of this big beast. Also installed the pusher fans from Enzo but this is more for looks than function.
Good luck,
Stretch
