I have no practical experience doing it, but I did do some research into how a stroked 351 could be EFIed. If you are going to use the stock computer, you will need to have a
Tweecer. There are also many other aftermarket computers and FMS's EPEC computers. All of these allow you to vary the program/tune that will be significantly different than the stock 302. Do a search on EFI and computer or ECU and computer.
