Hey guys! I currently have a 289 V8 in my 1966 mustang. I am looking at getting a bigger engine to put in. I was looking at a 302 or a 347. Does anyone know if I were to go with the 347 would I need to change anything in the engine bay such as motor mounts? I've read that with the 302 nothing needs to be changed but am not sure with the 347. If anyone could help that would be great!
