Vote 428 or aluminum 427FE??

My Edelbrocks were ported to a Stage 2 configuration. Is the info that you're providing for a "as cast" Edelbrock? CJ or MR?

If the BT heads didn't have raised exhaust ports, potentially requiring exhaust mods, there was a strong likelihood that I would have went that direction.

As cast. And apparently both flow the same, just different chamber volume. I think most of our builders "touch them up" a bit before putting them on though. But except for the big race cam, all of the old Ford cams stopped at .5 (when you subtract off the lash). Here's the page:
