I put a Hilborn system on a SBC (327), but the system I used was their EFI conversion that uses the same throttle bodies as their mechanical FI. This was a money-no-object project and we still could never get it to run as strongly and reliably as if it just had a single 4 barrel. It does look and sound pretty cool, but to get it run reasonably well we had to get rid of their Carbine ECU and replace it with a FAST XFI, Make a lower plenum, install an IAC, make all new throttle plates that actually fit the bores, add an IAT sensor in one of the stacks, etc, etc...

It runs pretty good now, but we could never get more than about 250 hp out of it.....which in this case works out to be about $80 per HP.
