I have a 97' mustang with several mods, nothing too major, i didnt want to jump into anything to fast, but i have an opportunity to perchase a new 306 with 400HP and 460LBs of torque. Should i buy the engine or just modify the engine i have now... 
Also for my year mustang (96-98) it wasnt as powerful as the newer ones, i've been told by a lot of people to put in 3.73's because the 4.10's would be too much for it, and why would it be too much?
Thanks for the input.
