How many of you has done the swap. 302/351?
Im interested to do the same...With injection.Or with carb(between the car tests) Is it worth the job?
What times do you run? Can I use my T-5? I heard that the T-5 is to week for the 351?

In my opinion, it is well worth it. It will cost you some $$, but you get stronger block, more torque, more power, etc...but it is heavier, so there are some slight disadvantages.

If you want the easiest swap possible using stock parts here's what you can do:
Get a 5.8L out of a truck, bronco or van (fuel injected).
I believe you can use the stock lower 5.8L intake manifold with the mustang upper intake manifold (the width of the lifter valley is different between the 302/351), but i'm not sure if the runner diameters are the same or similar. Some port matching would fix that, or buying a specific 5.8L swap intake manifold.
You'll NEED to get a special dual sump oil pan/pickup for the 351, reverse flow water pump, special accessory brackets (for serpentine belt to run the accessories because bolt holes line up differently in 302/351) and swap headers. You'll get alot more lowend torque and possibly close to 1/2 second less in the 1/4 mile.
the stock T5 for your year is rated for like 300ft/lbs of torque, but depending on how you treat it can last quite a while. Unless you plan on taking it to the dragstip and launching it at 5,000rpm with slicks i wouldn't expect the T5 to suddenly grenade.
Good luck!
