Big block chrysler 383 or 413
I am looking to put a big block in my 72 cuda, 440's are getting hard to find, have found several 413's and 383's. what would make the better build. Would like around 425-450 horse before the 200 shot of nitros. Have done several "stock" rebuilds, this will be my first performance build. I am setting the 340 off to the side. Is this an easy conversion from small block to big block? Any advice will be apreaciated
