Hey guys, im a relative newbie to this. I have a 1978 mustang II/ 302 engine that has been sitting up for about three years and i want to get it running well again. one of the cylinders is not getting enough preasure and therefore stalls out a lot. i think i want to change out the engine all together, so i would appreciate any specific advice anyone can share in that process... i am a city boy who knows nothing about cars so be gentle...

so good cost examples and engine suggestions and stores would be great. as well as options to make it run a lil more fuel efficient. i know, i know Dream on... lol...
Guys, thank you in advance for all he help
