Have a look at this conversion...  

 

BTW... no such thing as a 2001 996 C2S.

Wasfi ,  If you go with the stock rear end gears you'll leave all your tire rubber on the street, if you can afford it I would go with a 3:0 ring and pinion.  My car turns about 2,800 RPM's at 80 MPH, or red line 205 MPH.  If you don't change the ring and pinion you have too much HP for the low gears.

 

Renegade Hybrid in Las Vegas has the adapter housing and clutch assemblies to connect the 350 SBC to the Porsche transaxle.  I did all my own mechanical work, but the rub for me was mating the GM ECU to the Porsche instruments, etc.  I spent a lot of money with a couple of hi-tech guys to make everything work including the cruise control.  2 Things that still have a hiccup is the temp gauge and gas gauge.  I have a wide body car and the gas tank is configured differently, with a standard body car I don't you'll have that problem.  As far as the water temp gauge there is no fix for that, it will work for awhile, then quit, I reset it with my OBDII reader and it's good again.  I also installed a digital temp gauge as a backup.

 

This conversion isn't cheap if you do it right with new parts so don't be mislead, there's a lot of expenses to make the conversion "factory".  If you just want to go 0-60 with your hair on fire then that's another story.  I have a LS3 480 HP motor, and it's breath taking to drive...

 

Good luck, if I can help you further, just ask...  misery loves company...

Is that  DexCool in that reservoir?  That orange color sends shivers up my spine.

It is the orange stuff for aluminum engines...  Green for cast iron.
