383 or 406 small block?
I have a 69 chevelle STREET car w/ a TH400 and 3.73 12 bolt in the back. I want to build a 450-500HP motor,my original plan was a 383 stroker. I spoke to an engine builder he suggested a 406 small block to be more reliable because of a bigger displacement. I would like to know is a 406 a better choice over a 383 for reliablity and performance?
