My own: 440 crank offsetground to 3,9" BBC rods + .250" Flat top 454 pistons in any size. ? .060 -> 455 c.i. You need to make valve reliefs in the pistons. The crank prep is about the same as a 451/470 B stroker combo.
No superlight high $$$ parts here, just pieces to make cheap CI, as is the intention of using a 383 block.
