I have a 74 Bronco and I want to put a 351w in that bad boy. I was thinking of getting a engine from a junk yard or maybe autozone. If I get it out of a junk yard what should I look for in a 351w (id #) or what vehicle should it come out of?

 

after having done this a few times I would recomend going to a good reputable engine rebuilder and telling them what you want and paying the core charge!! It will save you a lot of time and headache, and even maybe money if the junkyard core is no good.
