Tunnel Ram I designed

I designed a new type of tunnel ram. I call it the Real Street Ram. In my dyno testing, it makes more torque than a dual-plane from right off idle. I've attached a graph of the torque curve vs. a dual plane on a stock Goodwrench 350 engine.

The biggest difference from a regular tunnel ram is that instead of having one huge plenum it has four small separate plenums. Only two runners connect to each plenum. I had to do a lot of work to get fuel distribution to be even between the cylinders. We used vacuum secondary 580CFM carburetors, so you can slam the throttle open even at <1500RPM.

Testing so far has been terrific. ****************

Hoping to get some technical discussion going.
