Purpleshaft .484 Cam in a 273?

The factory D Dart Cam had a .504 lift. That 340 cam is fine. Turbo would be a waste with the small cc, intake valve and intake runners. But you can pressurize anything and make HP. 273 responds with higher compression. My last NA 273 made 390 HP. I have some new pistons 10.5 and 12.0 if interested.
