Being new to this, I am sure this question is worn out. I want to put a flathead in my 31 Tudor. I cannot afford all the racing stuff, but rather just have a flathead that will fit with the least amount of mods to frame and drive train/chassis. I do want to change steering boxes, and a friend has a 32 B syncronized transmission he will give me. Do I need a 60 HP engine or would the 85 be a better choice. I am not worried about speed or horsepower, just want a smooth running ride. Also, do I need to change steering front axle and brakes? I have found an 85 HP engine for $500. Any guidance? Thanks!
