People have tried....I have a Callies block, and I was about to find out what mine will run tonight, and the track cancelled....But either way, I always worry about the valvetrain. I wish I knew what else I need to change on mine to go faster....But them be Hemi secrets nobody will tell you....If I could do it all over again, I would go with a moved centerline engine and more cubes....Not sure what the limit is...
