I drove the car to Daytona and something needs to be done and it definately has the wrong cam,going through the hills of KY and TN on I75 it would pull great if I was going over 70 and had not much power any slower. Its got a cam that wants to come on at around 2500 RPMs and it not good for a heavy car with a tall gear,its got 2.79 gears and have been watching for a center section with a set of 3.00 or 3.25s but found nothing so far and it might be cheaper to change the cam. I am planning on going back to a Y block but that might not happen untill a couple years after I round up all the parts so I need to get this motor to run better for the time being.
