Also great info here. Some people have told me I will have more clearance with headers and such if I go with a 440 block instead of the 383. Any thoughts here?
In some places, yes. Others, no. It's a crap shoot on what will fit better or not. The manifolds do fit better with a 383 on the passenger side. The driver side is better at the steering shaft with a 383, but the 440 gives more clearance to the power steering.
