"With respect to everyone's idea's..... If a tunnel ram were better, why doesn't everyone have one?"
I don't need to have ran one... Other posts show that they can be made to run well.
But I stand behind my statement.
Most cars are street cars. You can't beat the simplicity and effectiveness if a single carb set up on duel or single plane manifold on a street car.
A a single carb set up on duel or single plane manifold is easy to set up, maintain, fits under a closed hood, and can deliver equal power......... This is why so few run a tunnel ram.
