Not another 318 VS 360 Thread.

balancing internals is up to you. Detroit did it with formulas and neutral balanced components. All the variances stacked up, they still got away with it. 360's were spun after assembly and then balanced "after the fact" due to heavier rods and cranks. If you keep the 360 short block together and keep balancer and torque convert off same motor, your good. 318's were neutral balanced: Mix an match..Drive an LA based V6 Dodge pickup and then drive a Lexus LS4xx, you will feel what a balance job can do. Auto will absorb lots of imbalance, manual wont. Under 4500 is just not as crucial. Ever throw a weight off a tire, you can drive right through the imbalance, same with a motor. The initial cost is a little overwhelming, ~$175 but youll know you you are good to go afterwords. Just skip the titty bar that weekend ;-)
