Not sure what car shows you go to that everyone has cross ram hemis but they are better shows than here. I run a tunnel ram on my wedge and there are many here in town, nothing all that special. He could paint it pink and put a single carb on it and it would be baddass.
i've rarely seen tunnel rams on hemi's that aren't full blown track cars. usually it's cross rams or in the event there is, it's not some towering inferno dual quad piece.
wedges, sure. small blocks, of course. but a real deal hemi? not often.
