1. I have a 1988 F150 4.9L EFI engine in my '71 F100. I live in Central Queensland, Australia. Cold never comes here. I've heard of a tropical computer designed for use in warmer climates [Florida etc...] Can anyone enlighten me as to where to find such an item?
2. Would I benefit from a swap to an aftermarket HEI distributor [perhaps Summit or similar], or am I better off sticking with the original unit found standard with the EFI engine?
So you are running the whole EFI system? What are you concerned with? Does it run okay now?
I know California typically has more strict EPA laws and usually has more junk bolted on/computer calibrations to make it pass, but not sure about Florida having different computer setting?
Since the computer controls all the timing functions, you can't change the distributor.

You would have to invent one. Ford didn't produce anything like this. There was a unique computer for California, most of which is a warmer climate. But it had nothing to do with the warmer climate, California had unique emissions requirements. This computer was still 100% cold weather capable.
