I have not owned a high stall type torque converter, how streetable is it? I'm not taking my car to any drag strip as thats nowhere to be find here so this is a strictly supposed to be a fast car on the street not stand still launching. So far to my rough calculations a 4l80e is about 2 or 3 grand cheaper than a t56 magnum.
I can get a th350c with converter for about 2-3 grand cheaper than the 4l80e would cost to swap in.
Edit: By fast car i mean as long as it would technically go 14s in the 1/4 mile i would call it fast. Better said it would be a normal street car with reliable 450hp would be plenty for now
So true. I have already had to solder that once
