To C4 or C5?

Currently im in the break in period of my project. I have a 88 mustang lx with the supercharged V6 from a thunderbird. Most of you guys have been keeping tabs and feeding me input that has been very helpful but my questions continue

When I went looking for a tranny I wanted a C4 but instead some how picked up a C5 from a cougar. Its currently in the car and slips going into gears. Good thing I only paid $50 for it.

Heres my question I have the C5 thats in the car and I have a old 1966 C4 with the 24spline input shaft. Which tranny would be better to rebuild for my application. Or would it be better to find a newer C4from a mustang.

Just looking for some input on what tranny would be better.

The car is just a cruiser, Some 1/4 mile and road coarse. It will never run down the hwy.

For you guys running hi HP and torque is the C5 reliable.
any info will help
thanks
Doug

Keep in mind C4's also came in Torinos and other cars with a small block bolt pattern. They should be out there. I personally would go with a C4 over a C5 anyday.
