My stock 1988 5.0 mustang GT runs the quarter mile in the high 14 second range. Within the next few months I'm going to stroke it up to a 347 and supercharge it. How will this effect my quarter mile time? Do you think I could run in the low 12's?

Yes, But power means nothing if you cant get it to the ground. The tune and the parts you choose will also greatly affect the performance. How are you using the car? The suspention, as well as the entire driveline should be upgraded to take full advantage of your engine. Remember that the engine is only one part of the car and you need all the components working together to maximize performance and your 1/4 mile time.

I am gonna spend the extra money, get new suspension, new radiator and electric fan to cool, new aluminium drive shaft, and lots more just to cope with the stroke up. However a friend suggested I get a twin turbo. Which would be more effective, a supercharger or a twin turbo?

twin turbo are more effective at making power but they cost more and the install and tuning is a lil bit more involved than wit a supercharger.

Assuming your gonna do aftermarket h/c/i as well, you'll have MORE than enough power to run 10's and MORE than enough power to crack the stock block in half Had a friend with that set up and it went low 10's

Well yes, I am gonna get head cams and intake along with other things. This could crack the block in half eh? Scary, but imagine the power. What do you think I should do to avoid this?

Is there anyway I can keep my stock block, stroke it up, and supercharge it, without the risk of cracking the block?

Nitrous.
Use it only at the track.
Not as hard on the motor cus you only run it when you need it.

If you don't want to do that thank get a 351W out of a truck or something and build that insted.351 will handle more power.It's either that or your buying a FRPP or Dart Block (I didn't sportsman block because your stock block is that strong with some work).

yes a couple of things can help you. One have the block cleaned, hot tanked and magna fluxed to check for any cracks. The stocker is a a good canidate for an engine rebuild since the metal has been put through its heat cycle therefore the metal has cured so to speak and is stronger than a new block. It is what is known as a seasoned block. Two I'd add a good main support like the one dss sells or other that is just as thick. It will aid in preventing main cap walk which will crack the block. Finally a good tune is what you need if the engine is going to make it at all, any detonation will hurt the engine and end its life early.

Many above have said different blocks which is a great choice if you have the money. The sportsman is still a 2 bolt main but with stroger webbing in the casting, The dart block is a 4 bolt main but open up your check book for that one.
