In your original post, you never mentioned whether you were thinking of building a SB or BB replica, but you ought to consider building a nice simple 302 like Tim built for his SB ERA.

SBF's are cheaper to build and make good power. I'm sure Tim's car scoots well. And someday if more power is desired, you can upgrade to a bigger SBF (stroked Windsor) or a BBF (385 or FE).
