Any resin casters offer this carb/intake combo?

[Monty]

I've got numerous kits with big block Chevy engines but I'd like to add this intake manifold and side draft combo to one of them. 

These parts come in this kit

which I neither want nor need.

If you want to just buy the parts, Icemancollections offers a Chevy 572 Engine w/Cross Air Intake:

Not sure of anyone else offering it in 3D, but there might be.

If you have access to a 3D printer, there are a couple of sellers on Cults3D that offer different versions of the intakes that you can print yourself:

You can also try asking in the want section on here to see if someone might have one available.  Also, another kit that has a real nice intake like that is one of the Accurate Miniatures Grand Sport Corvettes.
