If that’s what you come up with, you need to be more creative.
Sure it is budget or not. They did it. Use your head.
The Dodge teams, Chrysler backed, NOT Chryslers money or engineers, let’s not blur that line like it’s a fact here, just used the same MoPar parts in the same catalog that you used to get. Except the cam and possibly/probably the pistons, all the W9 stuff is still available I think. If your or anyone else’s wallet isn’t as thick as it needs to be for such an endeavor….. well, I’m part of that club so pull up a chair and I’ll duck behind the bar and grab ya a beer.
Affording the parts is one thing. Knowing what to do with them is a mountain size difference.
Your pushing the idea that this would require a ton of money and rpm. I have only one word for that….
NOT!
In fact, if you do the math the 400 B engine is a better bang for the buck over an LA engine, both running stock displacements. Stroker kits for the BB are cheaper to boot.
