Big block swapping a 1964 barracuda

Good luck I hear the early A bodies ae challenging fitting things on em like exhaust etc. Not as forgiving as the 67 later body. Not saying it cant be done but there is a certain way to do it .
Yea it was a pain pulling manifolds off on the 318 small block it had so headers on a big block would be a nightmare. But with a single turbo out of the hood I just need super short ones and then it’s less of a headache with exhaust
