this is a throw together job to get going down the street..It is based off of what I HAVE or can trade out.
...I HAVE a M21 (fully rebuilt) that i drove before with my 400 and it SUCKED....even with the 3.73's...ended up putting in 4.56's. I defense of that statement....It was a good combo for point straight and SEND IT. Just not a very civil driving car.
