I probably have a dumb question, but here it goes. I have a 73 Dart with a 440/727. The engine is built as follows, 30 over, balanced, a true 10.1 c/r, Eddy heads, Eddy torker II intake, Holley 770, and a Comp 275 Dual energy cam. So the question is, are a set of 3.23's in in a 742 case strong enough to last with this combination? By the way the car is 100% street driven and I live in North Dakota. It's 50 miles to get any where around here so, the 3.23's are the gear of choice/neccesity.
