From how you describe your intended usage, why not use the factory injection? Waaayyy better mpg, throttle response etc.
Funny thing, we have a 67 GT vert that while it will end up with overdrive etc, we decided to go ahead and drop a 5.9 out of a Durango using the factory injection, larger cam and just minor engine mods. We planned to do this soon just to show how easy this is to do with the Tanks Inc FI tank and prebuilt harness. The 67 found us with a newly rebuilt but knocking 318 and fresh 904. Thought we could do a thread of what should be a couple of weekends swap.
