For the same amount of real money spent on redoing the 406 (or less) you can put the N/A 406 short block asside and build a simple low cost 355 short block with low compression. (You want 7.5:1)
Now you can add either the 144 or 177 blower + a solid flat tappet or roller cam that is
blower friendly + your 750HP to the 355 and go like hell.
You'd really really like the 177 blower on a 7.5:1 355cid. w 10+-12 psi boost. (2.33:1 drive ratio)
You will need diapers.
The low compression 355 is dirt simple to build and you will have the intact 406 short block as a spare ir for another use.
Use cam use a of the shelf solid flat tappet "blower" cam in it to save money of you want.
EG: a Crane F280-2 280-288 244-250 112lsa .518-.536 w 1.5's or .552"in .536"ex w a 1.6 1.5 split.
Or use a very good off the shelf crane street roller
EG: crane #118521 or 118531
A lunati voodoo street roller on a 112-113LSA 114LSA would be another good example
This 355-177 combo in your Camaro will eat your buds 142 blower car for lunch.
You can build this simple 355 yourself, in your garage.
In truth the off the shelf 110LSA Xe and voodoo solid street rollers work fine in 355 blower motors too.
But a 112-114 LSA version is only a phone call away.
The blown 355 is going to want to rev. Don't even waste your time with a Hyd cam for this.
