Generator vs. Alternator

[Scott Chadderdon]

I have a 55 with a 350 out of a 71 Chevelle. I put stock exhaust manifolds on it last night (ramhorns) replacing seriously worn out headers. The bracket for the generator worked fine with the headers installed, but now it will not work with the stock exhaust manifolds. I think I would like to change to an alternator. Can I just find a small block alternator bracket, buy an alternator and bolt it on and go? Is there anything else I need to do or look out for? Appreciate your help.
