I helped a friend last winter put a 1000 suzuki motorcycle carb on a 2.0 litre D-50 engine with a home made IR manifold and it ran pretty good

The reason for a IR manifold is driveability, you can run a big cam to make HP and still get it to idle smooth. It helps smooth out the TQ curve, low rpms the cylinders are not trying to pull the breath out of another cylinder and massive airflow at high rpms.

I think it could be fast, driveable and look awesome if done right

Right now there is about 18 inches snow on the roof of the cuda so.... wher is the twidling thumbs smiley?

I am not causing global warming, I am just trying to hold off a impending Ice Age!
