Not sure what is wrong with it, I am thinking plugged cat or injector, when I get motivated the cats are coming off and the fuel system is getting some ethonal thru it. That should clean some shit out

Its a 3.8 v6, so if you know someone with a v6 stang that needed a motor to rebuild or heads to use as a core...
Has 120k on the clock. I have run these motors to 200k in the past...
The radiator and exhaust system can go with the motor too...
I will also have 3.27's in 7.5" after I get my rear end done.
