351w and 5.0 t5 questions

1. The 5.0 and 351 share the same bolt pattern for the bellhousing, so it should bolt up no problem.

2 & 3. I believe it was either 89 or 90 that they upped the rating of the trans to somewhere in the neighborhood of 300ft lbs. The T5 really is the weak link in the drivetrain, so if you're looking at making a decent amount of power, you may want to look into one of the transmissions from g-force or astro performance if you plan on keeping a T5.

4. You may be right about it being light and reducing the risk of breaking the trans, but the possibility does still exist.

5. The 79-04 Mustangs didn't use a hydraulic clutch, so I'm not aware of any kits to adapt one to your application.

6. If you can find a complete pedal assembly (ebay or classifieds on here or corral), you could probably fabricate something easier than trying to piece together something similar.
