I bought a generic,whiplash cam to put in a 5.9 360 magnum but i dont have a degree wheel and also dont know how to degree a cam so my question is,should i just install it straight up(dot to dot) or should i advance it 4deg with my 9 way timing chain?also,what carb and intake do you experts recommend?motor runs good but has 98k on it,should i replace rod& main bearings when i swap cams or no?
