A friend gave me a low mileage 3o2 from a 93 Ford Pick up. I had a local shop go thru it and build it to my specs. He went to dyno it and asked me what it came out of. He then told me that I would have to run a C-6 instead of the C-4 I have already. He was told that the crank was balanced differntly. Can anyone tell me what the differnce is? Also can anyone recommend a C-6 and torque converter. Thanks
