CR around 10.1 or little higher. I think this would do good.

Well if you want a cam that sounds like it can take on the world look no further than the comp cams thumper series. Power wise not great , however you stated that was ok.. They sounds nasty as hell. I call them a good show boat cam I installed a 299 thumper for a buddy that has a 396 that is 9.5 comp ratio and its sounds wicked. Has decent manners and runs very well not a power house but he loves it. HYD roller is a nice upgrade I do not know if they make it in a flat tappet. But in the end no reason not to go to a hyd roller only makes sense really.
