Re: Plans for a 478 build.

So, how would the EFI work on a V-12. How would it be timed, crank trigger?

Re: Plans for a 478 build.

Since there's no HEI setup for the V12 it would have to be a crank trigger at the least. ThunderV12.com makes a coil pack to replace the distributor, I bet this setup will work with EFI. I would contact them:ok:

I wonder of that could be produced on a 3D printer.
