hey guys new to the forum. I am looking to put either a big block or a small block in a mustang. I really dont know much about what i can do but before i just go out buying stuff i thought i would talk to some people that have done it already. What would i need to put a small block in an older mustang gt and what mods should i do to the engine. I really dont know how to phrase the questions i have but what are thing i need to know about doing a project like that?
