Source for T5 for Swap

On my long to-do list for my '70 convertible, I plan on swapping from the C4 to a T5. I've been debating whether to buy new or search for a used T5 and rebuild it to handle some decent power.

Anway, the reason for this post is that I found a T5 locally for a good price, however it is out of a late 80's Fox body with a 4 cylinder.

Does the engine size of the source car (5.0 or 4 cylinder) matter? Putting it another way, did Ford use the same T5 in the 4 cylinder and 5.0 Mustangs?

I'll be hooking this up to either a 302 or 351W in my car (haven't decided yet).

Thanks!

Nevermind...found my answer on Moderndriveline's website:

Ford also used the T-5 in 2.3L cars through the years. While the 4 cylinder T-5 may appear to be the same, they are not. Most 4 cylinder T-5s received a 3.97 gear set with a .79 overdrive and small input pilot bearing shaft. Four cylinder T-5's should not be used behind a V-8, even when the pilot bearing id is decreased to match. Simply put, they will not hold up. Torque rating ~240ft/lbs. Besides first gear is much too low to be usable behind a high horse power
