I have a 68 455 and was curious if anyone has added a if system to theirs. Looking at the Holly terminator. Not looking to race the car just better drivability.

If you want a simple Fuel Injection system, try the FAST EZ EFI system. It will get you running good with very little issues. The system self tunes so you don't have to make adjustments. But it does not work for supercharged or turbo engines.
