Any letters after the C6AE? Like C6AE-E or something? Is it drilled for hydraulic lifters or is it a SFT? Really, the only thing that matters, if you're going to rebuild it, is the condition of the cylinders and whether it has the extra webbing on the crank saddle. FWIW, my galleys are blocked off anyway. Here's a page though that outlines some of the major differences between a CJ/SCJ and a PI. Comparison of Major 428 Engine Components | Mustang 428 Cobra Jet Registry The 428cobrajet.org site is probably the best site for pics/numbers/explanations on the different 428 components.

Check your block casting date and refer to this page: http://www.428cobrajet.org/id-block
