In my personal opinion which may be worth nothing because you sound more competent than myself when it comes to engineering such an idea, I think you would have a very narrow market to sell these, I was a Mopar guy years ago then converted to Chevy for several years and realized the error of my ways and now I am all Mopar once again, I am proud of my Mopars and wouldn't want to cross breed any of them with a Chevy race or not, lot of guys I am sure are purists like myself and take pride in mopar. I can see the idea and respect your ambition and you sound like an accomolished engine builder and or machinist, I am pretty sure I have seen big Chief pontiac heads used on big block Chevys before because they build more power? Maybe retro fit the new LS 427 or LS7 heads to the Mopar they are much better and make more power than the old style gen 2 big block heads and smaller. I don't think I could fit big block Chevy heads between my a body inner fenders anyway so you may be limited to full tube chassis cars thus limiting your selling market even more??? Also if a guy is going to spend big money on a new version block he probably isnt going to buy some used BBC heads off of the internet not knowing if they are cracked, milled etc. Just food for thought. Please don't be offended, I know submitting a patten is a headache and cost money as well.
