its only my opinion but it is realy up to you bro/?
you can build either one to do what you want...
the 327 was a great motor def one of my faves...
but the 350 is just as good in my opnion ...
if you start w/a good base you can do anything you want...w/the 350
ive ran both an its got alot to do with how there setup...
i personaly wont go bakwards when it comes to my cars...
if i start w/a 72 or something ill go forward,,,put a 89 vette settup in it or somethng like that....just me maybe but good luck bro

 

well i found out the motor i was looking at was garbage, but im starting to become a 327 fan knowing more about them, im gonna just build my 350, a buddy of mine whos a builds high performance motors has some ideas for my car imma talk with him this weekend and get a game plan
