Sence i have this new 71 318 swinger project, i've decided to just keep it SB, so i'll be building up a 360 most likely, i'm wanting to achieve mid. 12s NA or there abouts, i've heard good things about the 360 Magnum roller motors, would a good used one get the job done with the basic bolt-ons/converter/gears? Or would i be better off with the older 360 & just building it from scatch, i'll be useing the 904 trans.
