No your right. My velvet drives would need to be replaced with zf's. My motors are in boxes. I could lower the front quite a bit and possibly come up with the right angle. My motors run fine for now. I was just questioning for future reference. I think when the time comes I may just do the stroker crank setup on my 454's With no bore job it comes out to something near 480 cubes, cant remember the exact number.
