Good morning, I have a 69 dart with a stroke 440 with a 871 Wieland blower on it. I just bought this car and it is back halved with 33-19.5-15 tires on the rear. The front is to low for my liking, the oil pan is 3.5 inches off the ground. I would like to raise the front at least 2 to 2.5 inches. I do not know what size torsion bars that are in it right now. Nor do I know how to tell. Could someone recommend me a torsion bar size to do what I am looking for? I am going to race this once in a while but also drive it on the street. Thank you in advance.
