Just signed up today so i dont know too much about the site. I have a 03 mustang v6; mildly modded. Trying to see the best option for an engine swap. I was thinking a 351W would sound nice, only i dont know if i should get a short block, or a long block. What steps would i need to take to make sure the engine doesnt rip my little car in half. Any help would be appreciated.
