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.
