And a Cast CJ for Comparison.

A429 had a Victor intake and the cast CJ had a Mafia intake and smaller cam. It (iron CJ) peaked 200 rpm's higher, just saying. A couple of other differences where maybe header size and carburetor size (100cfm) and maybe tad of compression.

I thought these 2 were interesting. Same combo from a 466 to a 534 with ET's.

An old Kaase 519 pump gas build with a 4.437" bore from 1998.

As you can see they where ported all the way into the exhaust bolt hole.
