I have the Hurst Pro 5.0 shifter with the shifter stops on it. I was already in 3rd only going 45mph and when I kicked down on it and it REALLY started pulling BAM there it went. Torque . Thinking of the GM auto trans swap but I really hate to cut my exhaust. I have a full 3inch stainless system and I know it won't fit around the bell housing. I don't know if anyone has tried the full 3inch stainless system from CX Racing but it is a very nice system and bolts right up with no fab work or anything. Sounds awesome too. There isn't anyone around me that does mandrel bending but I will figure something out.
