Hi. I recently purchased a 69 amx. It has mostly everything besides the two main parts, the engine and trans. It was originally a 390 go pack, but i am having a difficult time deciding what i want to do. Some people say to find a 390/401 and just pay the money where as others are saying find a 360 and i will get almost the same performance if its worked over. Please give me your opinion on the subject. Thanks
