Big Block Chevrolet main bearing spacers...

One other option is Dart. You might be able to buy a Dart block with 409 mains. I have not done that, or tried. I have bought a Dart 396 block with a 54MM cam tunnel and with 0.904" lifter bores. The optional cam tunnel and lifter bores are around $250 or so, give or take. The wait on a Dart block can be up to 6-8 weeks.

I'm pretty sure a company such as Pro-Gram will probably make a set of caps, but I'm not sure who can or will make the upper spacers.
