Crazy numbers off a T5

So I spend the day pulling an engine and tranny out of an 87 mustang gt.
I am taking the t5 from the drivetrain and I just now went to identify it.

the bellhousing: E6ZR-6394-AA
the gear box: 13-52-065-908
the shifter: 13-52-066-918
also, stamped: basic 1B and in a circle stamped 89...

What do I have? Is it suitable behind a 351w with a 4barrel and torque cam?
He wants 100 bucks..

yeah it's only gonna be street. I got it from my friends 87 foxbody with an 89 302.
I have the bell housing and clutch from it as well. I basically took anything I wanted except the engine for 100bucks. So I'll be using the late model bell housing.

On another note, what's the story with having to shorten the drive shaft? I've heard both yes and no...

Why do you need to buy a new slip yolk at all ? Take the one off of your friends drive shaft. Installing this yolk might shorten the drive shaft's overall length, however it may or may not be enough.
