I am at the point that the engine and trans is going to be mocked up. How do you know how far back or forward to set it? I am putting a chevy 350 in a 29 tudor with a 2x4 frame. I will only need a single pulley off the crank for a lone alt, no ps or a/c. I am running elec fan and was thinking that moving the fan to the front of rad would give more room also. Any help is welcomed and appreciated as well as suggestions. Pics would be great of any setups similar. Thanks
