simple,just call schmidt and ask him to build u a mopar motor...that particular chevy head flows 508@.900 lift out of the box.i have seen b1 pso heads flow right around the 500 cfm mark with major work,so,looks like you would be behind the times at best.cyl head would be the major downfall here.but,youll never know unless you try.but be prepared to spend all your kids inheritance and hock the wifes jewels too....
