I've been mostly physically incapacitated in the short-term, so I've had time to endlessly surf the internet...some results.
If you swap in an EFI 5.8L and want to keep a long-runner intake, you have options from 3 manufacturers - Ford, Trick Flow Specialties, and Edelbrock.
If you stick with Ford - there is one option.
- Buy a 5.8L GT40 lower and GT40 upper.
These two intakes are the only ones known to fit under our hoods.
If you go with TFS - there are also 2 options.
1. Windsor Series
2. Box R-Series
Both series use the same lower, but the R-series upper is far more performance oriented. The R-series has shorter runners, no provision for EGR, and a 90mm TB opening. The Windsor series is available with either a 75 or 90mm TB opening. The 90mm option deletes EGR. They are all the same height (1" greater than the GT40 setup).
If you go with Edelbrock - there are 3 options.
1. Victor Series
2. Performer Truck lower with Performer 5.0 upper
3. Performer Truck lower with Performer RPM 5.0 upper
The Victor is the most radical route. It has no provision for EGR or PCV. It is also the tallest EFI intake available (1.5" higher than the GT40).
The Performer Truck lower and Performer/Performer RPM has provisions for EGR and PCV. The Performer RPM is the racier of the two. Height of these combos is unknown.

Nice to see your expanding your horizons, LOL.
DID this giveyou any ideas?
where is your source about the truck lower? i always thought the ports are not exactly the same shape. the truck lower has like a football shaped port, whereas the 302 mustang has an oval port.
You're right, the ports are different...as are the upper/lower bolt pattern. Mating them isn't feasible.
Has anybody seen a 351W intake comparison? I have seen countless 302/331/347 intake comparisons, but nary one for a 351.
