While the tunnel ram is not the most desired setup for the street it does attract alot of attention even now... Nothing like seeing it sticking through the hood and a couple of carbs on top with velocity stacks...
Still make`em quiver at the red lights...
I agree with Bumpstick. I have been running a tunnel ram on the street for over 20 years on both big and small block chevys. The key is the carbs and the ignition timing. To make a tunnel ram set up work very well on the street requires a completely different ignition curve than you are used to. Done right tunnels can be fun, streetable and intimidating.
